NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE A - BASIS OF PRESENTATION

     The accompanying unaudited, consolidated financial statements have been
prepared in accordance with instructions to Form 10-Q and, therefore, do not
include all information and footnotes normally included in financial statements
prepared in conformity with generally accepted accounting principles. They
should be read in conjunction with the financial statements of the company for
the fiscal year ended September 28, 1997.

     The accompanying financial statements include all adjustments (consisting
only of normal recurring accruals) that management considers necessary for a
fair presentation of its financial position and results of operations for the
interim periods presented.


NOTE B - EARNINGS PER SHARE

In 1997, the Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 128, Earnings per Share. Statement 128 replaced the
previously reported primary and fully diluted earnings per share with basic and
diluted earnings per share. Unlike primary earnings per share, basic earnings
per share excludes any dilutive effects of options, warrants and convertible
securities. Diluted earnings per share is very similar to the previously
reported fully diluted earnings per share. All earnings per share amounts for
all periods have been presented, and where necessary, restated to conform to the
Statement 128 requirements. Basic and diluted earnings per share were equivalent
to each other for the quarter ended December 28, 1997.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

SAFE HARBOR CAUTIONARY STATEMENT

From time to time, information and statements provided by the Company in filings
with the Securities and Exchange Commission, shareholder reports, press releases
and oral statements may include forward-looking statements which reflect the
Company's current views with respect to future events and financial performance.
Forward-looking statements are made pursuant to the safe harbor provisions of
the Private Securities Litigation Reform Act of 1995. Investors are cautioned
that all forward-looking statements involve risks and uncertainties, which could
cause actual results to differ materially from historical results or those
anticipated. The Company undertakes no obligation to publicly update or revise
any forward looking statements, whether as a result of new information, future
events or otherwise. Risks and uncertainties include, without limitation, the
Company's ability to open new restaurants profitably, changes in local, regional
and national economic conditions, especially economic conditions in the areas in
which the Company's restaurants are concentrated, increasingly intense
competition in the restaurant industry, increases in food, labor, employee
benefits and similar costs, and other risks detailed from time to time in the
Company's news releases, reports to shareholders and periodic reports filed with
the Securities and Exchange Commission.

The following table sets forth the percentage relationship to total revenues,
unless otherwise indicated, of certain items included in the Company's income
statements and operating data for the periods indicated:

NUMBER OF RESTAURANTS
 AT END OF QUARTER:
<TABLE>

<S>                                               <C>                    <C>
Company-owned Uno's - full service                95                     86
Franchised Uno's - full service                   66                     64
</TABLE>


Total revenue increased 6.7% to $45.0 million from $42.2 million last year.
Company-owned restaurant sales rose 6.8% to $41.6 million from $39.0 million
last year due primarily to a 9.1% growth in store operating weeks of
full-service Pizzeria Uno units resulting from the addition of nine restaurants
during the past four quarters. Comparable-store sales for Uno units for the
first three months of the fiscal year were 0.6% below the same period last year.
During the same period, average weekly sales, which includes sales at comparable
stores as well as new units, were 0.6% above last year, reflecting
higher-than-average sales levels for the nine new prototype units opened during
the past four quarters.

Consumer product sales rose slightly to $2.3 million for the first quarter of
fiscal 1998 as compared to $2.2 million in the first quarter last year. Sales to
food service providers were up as the company continued its initial shipments of
product to Sainsbury's Supermarket PLC. Sales volumes in the fresh retail and
wholesale segments have declined during the first quarter due in part to a
reduction in promotional activities and an increase in competition in the
supermarket segment.

Franchise income, which includes royalty income and initial franchise fees,
increased slightly to $1,072,000 from $1,035,000 last year. Royalty income
increased 6.4% as operating weeks increased 4.9% and average weekly sales
improved by 2.8% for the first three months of the fiscal year. One full-service
restaurant was opened during the quarter and six new full-service units have
been added during the past four quarters.

Cost of food and beverage as a percentage of restaurant and consumer product
sales dropped slightly to 25.8% this year from 26.0% last year. Slightly lower
cheese costs this year versus last year contributed to the cost reduction for
the quarter. Labor and benefits as a percentage of restaurant and consumer
product sales dropped by 10 basis points from the prior year. Increases in the
average wage rate, primarily from the September 1997 minimum wage increase, were
more than offset by savings achieved from lower benefit cost. Occupancy costs
and other operating expenses declined slightly, principally due to operating
leverage associated with higher average unit volumes. General and administrative
expenditures were up less than 1% from a year ago, however, as a percentage of
total revenues these expenses declined to 7.0% from 7.4% last year. Depreciation
and amortization expenses as a percentage of restaurant and consumer product
sales increased to 7.5% from 7.3% last year principally due to higher
amortization of pre-opening costs as the Company's unit growth rate has
increased slightly versus the prior year.

Operating income for the first quarter of the fiscal year increased 20.4% to
$2,726,000 from $2,265,000 last year. The operating margin for the period
increased to 6.1% from 5.4%. The increase in operating income and margin are
based on the factors mentioned above.

Other expense of $923,000 increased from $610,000 last year. Interest expense
increased from $621,000 last year to $884,000 this year due to higher debt
level. The increase in debt levels was a result of the Company's share
repurchase program completed in the fourth quarter of fiscal 1997. The effective
tax rate of 33% for the quarter compared favorably to last year's rate of 34%
due in part to the impact of various tax credits. Net income increased to
$1,208,000 from $1,092,000 last year based on the factors noted above.

Historically, the Company has leased most of its restaurant locations and
pursued a strategy of controlled growth, financing its expansion principally
from operating cash flow, public equity offerings, the sale of senior, unsecured
notes, and revolving lines of credit. During the first quarter of fiscal 1998,
the Company's investment in property, equipment and leasehold improvements was
$3.6 million.

The Company currently plans to open approximately six restaurants in fiscal
1998. The Company expects that the average cash investment required to open a
full service Pizzeria Uno restaurant, excluding land and pre-opening costs, will
be approximately $1.6 million.

On November 4, 1997 the Company entered into a $55 million credit facility (the
"$55 million facility") to replace its $50 million revolver. The $55 million
facility consists of three components, a $26.6 million unsecured revolver, a $20
million secured mortgage facility and a $8.4 million term loan. The $26.6
million unsecured revolver is due in October 2002. The $20 million secured
mortgage facility is due in 27 quarterly installments of $500,0000 plus interest
commencing on January 31, 1998 with a final installment of the outstanding
principal plus interest due in October 2004. The $8.4 million term loan is due
in 20 quarterly installments of $420,000 plus interest commencing on January 31,
1998. Amounts borrowed under the $55 million facility accrue interest at
variable rates based on, at the election of the Company, either the LIBOR plus
100-175 basis points or prime plus 0-50 basis points. The agreement contains
certain financial covenants including a cash flow coverage ratio and a
consolidated leverage ratio. The

Company anticipates using the unsecured revolver of the $55 million facility for
the development of additional restaurants and for working capital needs. The
Company used the proceeds of the $20 million secured mortgage facility component
to refinance certain owned properties and used the $8.4 million term loan
component to finance the "Dutch Auction" tender offer completed in the fourth
quarter of fiscal 1997. As of December 28, 1997, the Company had outstanding
indebtedness of $42.9 million under its $55 million revolving credit and term
loan agreement, $4.9 million under its MetLife Capital mortgage program, and
$1.0 million in capital lease obligations.

In December 1997, the Board of Directors of the Company authorized the
repurchase of up to 500,000 shares of the Company's Common Stock in the market
from time to time. The shares of Common Stock to be purchased will be held in
treasury and may be used by the Company from time to time for its employee
benefit plans. The Company did not repurchase any stock during the first fiscal
quarter and currently has 2.8 million shares in its treasury account.

The Company believes that existing cash balances, cash generated from operations
and borrowings under its mortgage commitment and revolving line of credit will
be sufficient to fund the Company's capital requirements for the foreseeable
future.

The company is currently obligated under 92 leases, including 90 leases for
Company-owned restaurants and two leases for its executive offices. The Company
is currently negotiating the renewal of a lease for an office building
containing one of its restaurants and continues to pay rent on a tenancy at will
basis in the interim.


IMPACT OF INFLATION

Inflation has not been a major factor in the Company's business for the last
several years. The Company believes it has historically been able to pass on
increased costs through menu price increases, but there can be no assurance that
it will be able to do so in the future. Future increases in local area
construction costs could adversely affect the Company's ability to expand.


SEASONALITY

The Company's business is seasonal in nature, with revenues and, to a greater
degree, operating income being lower in its first and second fiscal quarters
than its other quarters. The Company's seasonal business pattern is due to its
concentration of units in the Northeast, and the resulting lower winter volumes.
