          ----------------------------------

Ladies and Gentlemen:

     We have acted as counsel to Domino's, Inc., a Delaware corporation (the
"Company"), and Domino's Pizza International, Inc., a Delaware corporation (the
"Subsidiary Guarantor"), in connection with (i) the proposed issuance by the
Company of up to $275,000,000 aggregate principal amount of its 10 3/8% Series B
Senior Subordinated Notes due 2009 (the "Exchange Notes") registered under the
Securities Act of 1933, as amended (the "Securities Act"), in exchange for a
like principal amount of the Company's outstanding 10 3/8% Senior Subordinated
Notes due 2009 (the "Original Notes"), which have not been so registered (the
"Exchange Offer") and (ii) the guarantee of the Exchange Notes by each of the
Guarantors (as defined below) (the "Guarantees").

     The Exchange Notes will be issued under an Indenture dated as of December
21, 1998 (the "Indenture") among the Company and Domino's Pizza, Inc., Metro
Detroit Pizza, Inc., Domino's Franchise Holding Co., Domino's Pizza
International Payroll Services, Inc., Domino's Pizza - Government Services
Division, Inc. and the Subsidiary Guarantor (collectively, the "Guarantors") and
IBJ Whitehall Bank & Trust Company (formerly IBJ Schroder Bank & Trust Company),
as indenture trustee.  The terms of the Guarantees are contained in the
Indenture, and the Guarantees will be issued pursuant to the Indenture.

     We have examined and relied upon the information set forth in the
Registration Statement on Form S-4 (the "Registration Statement") filed by the
Company and the Guarantors with the Securities and Exchange Commission relating
to the Exchange Offer and the Guarantees and such other documents and records as
we have deemed necessary and have made such investigation of fact and such
examination of law as we have deemed appropriate in order to enable us to render
the opinions set forth herein.  As to questions of fact not independently
verified by us, we have relied upon certificates of officers of the Company and
the Subsidiary Guarantor, public officials and other appropriate persons.

     We express no opinion as to the laws of any jurisdiction other than those
of The Commonwealth of Massachusetts, the corporate laws of the State of
Delaware and the federal laws of the United States of America.  We call your
attention to the fact that each of the Indenture, the Exchange Notes and the
Guarantees provides that it is to be governed by and construed in accordance
with the internal laws of the State of New York.  We are of the opinion that a
Massachusetts court or a federal court sitting in Massachusetts would, under
conflict of law principles observed by the courts of Massachusetts, give effect
to such provisions.  For purposes of the opinion expressed herein, we have
assumed that each of the Indenture, the Exchange Notes and the Guarantees
provides that it is to be governed by would be governed by and construed in
accordance with the internal laws of The Commonwealth of Massachusetts.

     We express no opinion as to whether the Subsidiary Guarantor may guarantee
or otherwise become liable for indebtedness incurred by the Company, including,
without limitation, indebtedness evidenced by the Exchange Notes, except to the
extent the Subsidiary Guarantor may be determined to have benefitted from the
incurrence of such indebtedness by the Company, or as to whether such benefit
may be measured other than by the extent to which the proceeds of the
indebtedness incurred by the Company are directly or indirectly made available
to the Subsidiary Guarantor for its corporate purposes.

     Based upon the foregoing, we are of the opinion that the Exchange Notes
have been duly authorized by all requisite corporate action of the Company and,
when executed and authenticated in the manner provided for in the Indenture and
delivered against surrender and cancellation of a like aggregate principal
amount of Original Notes in accordance with the terms of the Exchange Offer, the
Exchange Notes will constitute valid and binding obligations of the Company
entitled to the benefits of the Indenture and enforceable against the Company in
accordance with their terms, except as enforcement thereof may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws of
general application affecting the rights and remedies of creditors or by general
principles of equity, regardless of whether applied in proceedings in equity or
at law.  We are of the further opinion that the Guarantee by the Subsidiary
Guarantor has been duly authorized by all requisite corporate action of the
Subsidiary Guarantor and, upon the due issuance of the Exchange Notes in
accordance with the terms of the Indenture and the Exchange Offer, such Exchange
Notes shall be entitled to the benefits of the Guarantee by the Subsidiary
Guarantor which will constitute a valid and binding obligation of the Subsidiary
Guarantor, enforceable against the Subsidiary Guarantor in accordance with its
terms, except as enforcement thereof may be limited by bankruptcy, insolvency,
reorganization, moratorium or other similar laws of general application
affecting the rights and remedies of creditors or by general principles of
equity, regardless of whether applied in proceedings in equity or at law.
