       Re: Atlantic Coast Entertainment Holdings, Inc. Registration Form S-4

Ladies and Gentlemen:

             We have acted as counsel to Atlantic Coast Entertainment Holdings,
Inc., a Delaware corporation (the "Company"), in connection with the public
offering by the Company of up to 10,000,000 shares (the "Shares") of the
Company's common stock, par value $0.01 per share (the "Common Stock") and up to
$110,000,000 principal amount of 3% Notes due 2008 (the "Notes", and together
with the Common Stock, the "Securities").

             This opinion is being furnished in accordance with the requirements
of Item 601(b)(5) of Regulation S-K under the Securities Act of 1933, as amended
(the "Act").

             In connection with this opinion, we have relied as to matters of
fact, without investigation, upon certificates and written statements of certain
officers of the Company. We have also examined originals or copies, certified or
otherwise identified to our satisfaction, of such instruments, documents and
records as we have deemed relevant and necessary to examine for the purpose of
this opinion, including (i) the Registration Statement on Form S-4 (File
No.333-110485) filed with the Securities and Exchange Commission (the
"Commission") on November 14, 2003 under the Act (such Registration Statement,
as so amended, being hereinafter referred to as the "Registration Statement");
(ii) a form of the proposed Notes; (iii) the form of the proposed Indenture, by
and among the Company, as issuer, ACE Gaming, LLC, as guarantor, and the
trustee, governing the Notes (the "Indenture"); (iv) the Amended and Restated
Indenture, dated as of October 12, 2001, by and among GB Property Funding Corp.,
as issuer, GB Holdings, Inc. and Greate Bay Hotel and Casino, Inc., as
guarantors, and Wells Fargo Bank Minnesota, National Association ("Wells
Fargo"), as trustee, governing the 11% Notes due 2005 issued by GB Property; (v)
the form of the proposed Amendment to the Amended and Restated Indenture by and
among GB Property, as issuer, GB Holdings and Operating, as guarantors, and
Wells Fargo, as trustee; (vi) the form of the proposed Second Amended and
Restated Indenture by and among the Company and Wells Fargo, as trustee, (vii)
the Certificate of Incorporation of the Company, as presently in effect; (viii)
the By-Laws of the Company, as presently in effect; (ix) the form of the
proposed Contribution Agreement by and among GB Holdings, the Company,
Operating, and ACE, (x) the form of the proposed Merger Agreement among GB
Holdings, GB Property and Operating and (xi) certain resolutions of the Board of
Directors of the Company relating to the issuance and sale of the Securities and
related matters.

             In connection with this opinion, we have assumed the legal capacity
of all natural persons, the accuracy and completeness of all documents and
records that we have reviewed, the genuineness of all signatures, the due
authority of the parties signing such documents, the authenticity of the
documents submitted to us as originals and the conformity to authentic original
documents of all documents submitted to us as certified, conformed or reproduced
copies. In making our examination of documents executed or to be executed by
parties other than the Company, we have assumed that such parties had or will
have the power, corporate or other, to enter into and perform all obligations
thereunder, and have also assumed the due authorization by all requisite action,
corporate or other, and the execution and delivery by such parties, of such
documents and the validity and binding effect thereof.

             Based upon and subject to the foregoing, it is our opinion that:

       1. When (i) the Registration Statement becomes effective and the
Indenture has been qualified under the Trust Indenture Act of 1939, as amended;
(ii) the Indenture has been duly executed and delivered; and (iii) the Notes
have been duly executed and authenticated in accordance with the terms of the
Indenture, the issuance of the Notes will have been duly authorized, and the
Notes will be 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 to the extent that (a) enforcement thereof may be limited by
(1) bankruptcy, insolvency, reorganization, receivership, fraudulent conveyance,
moratorium, or other similar laws now or hereinafter in effect relating to
creditors' rights generally and








(2) general principles of equity (regardless of whether enforceability is
considered in a proceeding at law or in equity) and (b) the waiver contained in
Section 513 of the Indenture may be deemed unenforceable; and

       2. When issued in accordance with the terms of the Indenture, the Shares
will be validly issued, fully paid and nonassessable.

             We also note that the Securities are subject to forfeiture and
certain other restrictions under certain provisions of New Jersey law as
described in the Registration Statement and insofar as our opinions may relate
to matters governed by the laws of the State of New Jersey, we have relied,
without further investigation, upon the opinion of Sterns & Weinroth as local
counsel, a copy of which is attached hereto as Exhibit A.

             Our opinion expressed above are limited to the laws of the State of
New York, the General Corporation Law of the State of Delaware, including the
applicable provisions of the Constitution of the State of Delaware and the
reported judicial decisions interpreting such laws and provisions. In addition,
we express no opinion herein concerning any statutes, ordinances, administrative
decisions, rules or regulations of any county, town, municipality or special
political subdivision (whether created or enabled through legislative action at
the federal, state or regional level). This opinion is given as of the date
hereof and we assume no obligation to advise you of changes that may hereafter
be brought to our attention.

             We hereby consent to the filing of this opinion with the Commission
as an exhibit to the Registration Statement. We also consent to the reference to
our firm under the caption "Legal Matters" in the Registration Statement. In
giving this consent, we do not thereby admit that we are included in the
category of persons whose consent is required under Section 7 of the Act or the
rules and regulations of the Commission.

                                               Very truly yours,

             SECURITIES AND EXCHANGE COMMISSION ("COMMON STOCK REGISTRATION
             STATEMENT")

Gentlemen:

             We have acted as special regulatory counsel on gaming matters in
the State of New Jersey to Atlantic Coast Entertainment Holdings, Inc.
("Atlantic") and ACE Gaming, LLC ("ACE", with Atlantic, the "Companies"), in
connection with the above-referenced Note Registration Statement and Common
Stock Registration Statement (the "Registration Statements") with respect to
matters relating to the New Jersey Casino Control Act, N.J.S.A. 5:12-1 et seq.,
to regulations promulgated thereunder, N.J.A.C. 19:40-1.1 et seq. and the
decisions of the Casino Control Commission thereunder ("New Jersey Gaming
Laws"). Capitalized terms used but not otherwise defined herein shall have the
respective meanings ascribed to them in the Registration Statements.

             In connection with this opinion, we have reviewed originals or
copies, certified or otherwise identified to our satisfaction, of the following
documents:

                   (a)    Note Registration Statement;

                   (b)    the Common Stock Registration Statement; and

                   (c)    the Certificate of Incorporation of Atlantic.

             We have also examined such other documents as we have considered
necessary or appropriate under the circumstances to render the opinions below.
In such examination, we have assumed the genuineness of all signatures, the
legal capacity of natural persons, the authenticity of all documents submitted
to us as originals, and the conformity and completeness to authentic original
documents of all documents submitted to us as certified, conformed or
photostatic copies.

             In rendering the opinion below, the scope of our review has been
limited to a review of the New Jersey Gaming Laws. We do not hold ourselves out
as experts in and express no opinion as to the laws of any state or jurisdiction
other than New Jersey Gaming Laws. Accordingly, this opinion is confined to such
matters as are governed by New Jersey law.

             Based upon the foregoing, and subject to the qualifications,
limitations, exceptions and assumptions hereinafter set forth, it is our opinion
that the provisions contained in section EIGHTH of the Certificate of
Incorporation of Atlantic regarding redemption of the securities of the
Corporation are required by the New Jersey Gaming Laws and such provisions and
restrictions are accurately described in the Registration Statements.

             (a) We express no opinion herein with regard to any authorizations,
consents, or approvals of the Commission which may be required in connection
with the consummation of the transactions contemplated by the Registration
Statements.
