             NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                  (Unaudited)

1.   INTERIM FINANCIAL PRESENTATION

     The interim consolidated financial statements are prepared pursuant to the
     requirements for reporting on Form 10-Q. These financial statements have
     not been audited by independent accountants. The December 26, 1999 balance
     sheet data was derived from audited financial statements but does not
     include all disclosures required by generally accepted accounting
     principles. The interim financial statements and notes thereto should be
     read in conjunction with the financial statements and notes included in the
     Company's Form 10-K dated December 26, 1999. In the opinion of management,
     these interim financial statements reflect all adjustments of a normal
     recurring nature necessary for a fair statement of the results for the
     interim periods presented. The current period results of operations are not
     necessarily indicative of results which ultimately will be reported for the
     full year ending December 31, 2000.

     Certain prior year amounts have been reclassified to conform to current
     year presentation.

2.   PREOPENING COSTS

     In accordance with AICPA Statement of Position (SOP) 98-5, "Reporting on
     the Costs of Start-Up Activities," the Company expenses all start-up and
     pre-opening costs as they are incurred.

3.   FUTURE ACCOUNTING REQUIREMENTS

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
     Instruments and Hedging Activities". This Statement requires that all
     derivative instruments be recorded on the balance sheet at their fair
     value. Changes in the fair value of derivatives will be recorded each
     period in current earnings or other comprehensive income, depending on
     whether a derivative is designated as part of a hedge transaction and, if
     it is, the type of hedge transaction. The new rules will be effective the
     first quarter of 2001. The new standard will not have a material impact on
     the Company's financial statements.

4.   REVERSE STOCK SPLIT

     On August 9, 1999, the Company effected a 1-for-4 reverse stock split of
     the Company's common stock. All share and per share data have been restated
     to reflect the reverse stock split.

5.   SUBSEQUENT EVENTS

On July 11, 2000 the Company made a strategic decision to close and closed, its
Pizzeria Uno restaurant in Media, Pennsylvania due to declining operations.
Management does not anticipate significant losses due to the closure.

In July 2000, the holder of Series I Convertible Preferred Stock converted 1,000
shares of preferred stock into 200,000 shares of common stock.

On August 1, 2000 the Company received a $400,000 loan from private individuals.
The loan bears interest at 9% and is payable in monthly installments over the
next four years. In connection with the loan, the Company issued 40,000
warrants.

Item 2.   Management's Discussion and Analysis of Financial Condition and
          Results of Operations.

The following discussion and analysis should be read in conjunction with the
Company's financial statements and notes thereto included elsewhere in this Form
10-Q. Except for the historical information contained herein, the discussion in
this Form 10-Q contains certain forward looking statements that involve risks
and uncertainties, such as statements of the Company's plans, objectives,
expectations and intentions. The cautionary statements made in this Form 10-Q
should be read as being applicable to all related forward statements wherever
they appear in this Form 10-Q. The Company's actual results could differ
materially from those discussed here. For a discussion of certain factors that
could cause actual results to be materially different, refer to the Company's
Annual Report on Form 10-K for the year ended December 26, 1999.

(1)   When computing comparable restaurant sales, restaurants open for at least
      12 months are compared from period to period.

Material Changes in Results of Operations for the Three and Six Months Ended
June 25, 2000 as compared to the Three and Six Months Ended June 27, 1999

During the 2000 period, the Company, through its 50% partnership interest,
operated a Daily Grill Short Order at Universal Studios CityWalk. The results of
that restaurant are reported under the equity method and, therefore, are not
included in consolidated revenues or operating results, other than management
fees from that restaurant. Additionally, the 2000 periods include two weeks of
operations of the Company's newly opened Chicago - The Grill on the Alley
restaurant.

Revenues

Revenues for the second quarter of fiscal year 2000 increased to $ 10.3 million,
or 7.3% over the $ 9.6 million generated for the same quarter of fiscal 1999.
Revenues for the six months ended June 25, 2000 rose 6.6% to $ 21.2 million from
the $ 19.9 million generated for the same period of fiscal year 1999. Total
revenues included $ 10.2 million of restaurant sales revenues and $ 146,000 of
management and licensing fees for the second quarter and $ 20.9 million of
restaurant sales revenues and $ 296,000 of management and licensing fees for the
first six months of 2000. This compares to $ 9.5 million of restaurant sales
revenues and $ 111,000 of management and licensing fees for the 1999 quarter and
$ 19.6 million of restaurant sales revenues and $ 236,000 of management and
licensing fees for the first six months of 1999. The increase in restaurant
sales revenues for both the quarter ($ 0.7 million, or 7.4 %) and the six months
($ 1.3 million, or 6.6%) was primarily attributable to an increase in same store
sales, plus two weeks of sales ($249,000) at the Chicago Grill on the Alley,
which opened in June 2000.

Same store sales (for restaurants open at least 12 months) increased 5.2 % for
the quarter and 5.1% for the six-month period. The increase in management and
licensing fees for both the quarter ($ 35,000, or 31%) and the six months
($ 60,000, or 25%) was primarily attributable to the additional fees from the
Universal CityWalk Daily Grill, which opened in July 1999.

In addition to the restaurants owned by the Company, which sales are
consolidated and included in the results of operations for the Company, the
Company manages four other restaurants. Total

                                       8
<PAGE>

revenues for all 19 restaurants owned and managed by the Company were
$12,738,000 and $11,498,000 for the three months and $25,930,000 and $23,015,000
for the six months ended June 2000 and 1999, respectively. This represents an
increase of $1,241,000, or 10.8% and $2,915,000 and 12.7%, respectively.

Cost of Sales

Cost of sales increased by 12.4 % for the quarter and 9.5 % for the six months
ended June 25, 2000 as compared to the same periods in 1999. As a percentage of
sales revenues, cost of sales was 28.4% for the quarter and 28.1 % for the six
months as compared to 27.3 % for the second quarter of 1999 and 27.3 % for the
year-to-date period in 1999. The increase in cost of sales as a percentage of
sales during the 2000 three and six month periods was primarily attributable to
higher food costs associated with the San Jose Grill and the Beverly Hills Grill
Restaurants.

Restaurant Operating Expenses

Restaurant operating expenses increased by 6.7 % for the quarter and 5.8 % for
the six months as compared to the same periods in 1999. The dollar increase in
restaurant operating expenses was primarily attributable to additional sales in
same stores. However restaurant operating expenses, as a percentage of revenues,
decreased in the second quarter from 58.9% in 1999 to 58.2% in 2000. For the
six-month periods, the percentages were 58.6% in 1999 and 58.2% in 2000. The
decrease in restaurant operating expenses as a percentage of total revenues was
primarily attributable to the spreading of fixed costs over higher same store
sales. The increase in management fees also favorably affected these
percentages.

General and Administrative Expense

General and administrative expense increased 9.7 % for the quarter and 4.6 % for
the six month period as compared to the same periods in 1999. As a percentage of
total revenues, general and administrative expense totaled 8.5 % for the quarter
and 7.9 % for the six month period as compared to 8.3 % for the quarter and
8.1 % for the six month period in 1999. The increase in total general and
administrative expense during 2000 of approximately $75,000 for both the quarter
and six month periods, was primarily increased corporate salaries.

Depreciation and Amortization

Depreciation and amortization expense increased by 4.8 % for the quarter and
2.2 % for the six month period as compared to 1999. The small increase in
depreciation and amortization expense was primarily attributable to the opening
of the Chicago Grill in June of 2000.

Preopening Costs

All preopening costs incurred during the periods relate to the opening of
Chicago-The Grill on the Alley, in June 2000, and were expensed as incurred.

Minority Interest and Equity in Loss of Joint Venture

The three and six month expenses also reflect a net minority interest in the
(earnings) and losses of

                                       9
<PAGE>

subsidiaries of $201,000 and $168,000 respectively, compared with a ($10,000)
and ($28,000) in the same periods in 1999. This resulted primarily from losses
at the Chicago Grill on the Alley partially offset by income at the San Jose
Grill.

The Company incurred a charge of $9,000 for its equity in loss of joint venture
during the three and six month periods of 2000, which reflects the Company's 50%
interest in the Daily Grill Short Order at Universal Studios City Walk.

Dividends

The Company reported dividends on preferred stock of $12,500 in each of the
three month periods and $25,000 in each of the six month periods ended June 25,
2000 and June 27, 1999.

Interest Expense, Net

Interest expense, net, decreased by 13 % during both the quarter and six-month
periods compared to the same periods in 1999. The decrease in interest expense
was primarily attributable to reduced borrowing during 2000.

Net Income

Net income was negatively impacted by the one time preopening costs incurred at
Chicago-The Grill on the Alley. Without such one time charge, net income would
have been $317,000 for the quarter and $626,000 for the six months as compared
to $110,000 for the quarter and $372,000 for the six months ended June 27, 1999.

Material Changes in Financial Condition, Liquidity and Capital Resources.

At June 25, 2000 the Company had negative working capital of $ 3.4 million and a
cash balance of $0.6 million compared to negative working capital of $3.7
million and a cash balance of $0.4 million at December 26, 1999. The change in
working capital was primarily attributable to a significant reduction in current
debt.

The Company's need for capital resources has resulted from, and for the
foreseeable future is expected to relate primarily to, the construction of
restaurants. Historically, the Company has funded its day-to-day operations
through its operating cash flow, while funding growth through a combination of
bank borrowing, loans from stockholders/officers, the sale of Debentures, the
sale of Preferred Stock, the issuance of warrants, loans and tenant allowances
from certain of its landlords and through joint venture arrangements. At June
25, 2000, the Company had existing bank borrowing of $ 1.5 million, a loan from
a San Jose Grill L.L.C. member of $ 0.1

                                       10
<PAGE>

million, an SBA loan of $ 0.1 million, loans from stockholders/officers of $ 0.7
million, equipment loans of $ 1.6 million and loans/advances from a landlord of
$ 0.1 million.

On August 1, 2000 the Company received a $400,000 Loan from private individuals.
The Loan bears interest at 9% and is payable in monthly installments over the
next four years. In connection with the loan, the Company issued 40,000
warrants.

In July 2000 the holder of Series I Convertible Preferred Stock converted 1,000
shares of preferred stock into 200,000 shares of common stock.

As of June 25, 2000 the Company had opened a majority owned hotel-based The
Grill restaurant in the Chicago Westin Hotel. The cost to construct the Chicago
Grill was $3.4 million.

Management anticipates that new non-hotel based restaurants will cost between $1
million and $2 million per restaurant to build and open depending upon the
location and available tenant allowances. Hotel based restaurants may involve
remodeling existing facilities, substantial capital contributions from the hotel
operators and other factors which will cause the cost to the Company of opening
such restaurants to be substantially less than the Company's cost to build and
open non-hotel based restaurants.

The Company may enter into investment/loan arrangements in the future on terms
similar to the San Jose Fairmont Grill and Chicago Westin Grill arrangements to
provide for the funding of selected restaurants. Management believes that the
Company has adequate resources on hand and operating cash flow to sustain
operations for at least the following 12 months. In order to fund the opening of
additional restaurants, the Company will require, and intends to raise,
additional capital through additional bank borrowings, the issuance of debt or
equity securities, or the formation of additional investment/loan arrangements,
or a combination thereof. The Company presently has no commitments in that
regard.

Future Accounting Requirements

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities". This Statement requires that all derivative
instruments be recorded on the balance sheet at their fair value. Changes in the
fair value of derivatives will be recorded each period in current earnings or
other comprehensive income, depending on whether a derivative is designated as
part of a hedge transaction and, if it is, the type of hedge transaction. The
new rules will be effective the first quarter of 2001, as amended by SFAS No.
137 in June 1999. The Company does not believe that the new standard will have a
material impact on the Company's financial statements.

Certain Factors Affecting Future Operating Results

In addition to the opening of a new restaurant during 2000, as described above,
and the various factors described in the Company's Annual Report on Form 10-K
for the year ended December 26, 1999, the following developments during the
first half of this year may impact future operating results.

On July 11, 2000 the Company made a strategic decision to close, and closed, its
Pizzeria Uno restaurant in Media, Pennsylvania due to declining operations.
Management does not anticipate incurring significant losses due to the closure.

The Company continues its efforts to sell its Pizza Restaurants.

There can be no assurance that the Company will be successful in opening new
restaurants in accordance with its anticipated opening schedule; that sufficient
capital resources will be available to fund scheduled restaurant openings and
start-up costs; that new restaurants can be operated profitably; that hotel
restaurant management services will produce satisfactory cash flow and operating

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

The Company is exposed to market risk from changes in interest rates on funded
debt. This exposure relates to its $2,100,000 revolving credit and term loan
facility (the "Credit Facility"). Borrowings outstanding under the Credit
Facility totaled $ 1,500,000 at June 25, 2000. Borrowings under the Credit
Facility bear interest at the lender's reference rate plus 0.25%. A hypothetical
1% interest rate change would not have a material impact on the Company's
results of operations.
