         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 2,750,000 shares (the "Shares") of the
Company's common stock, par value $0.01 per share (the "Common Stock") and up to
______ warrants to purchase Common Stock (the "Warrants", 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-_______) filed with the Securities and Exchange Commission (the
"Commission") on _____, ___ under the Act (such Registration Statement, as so
amended, being hereinafter referred to as the "Registration Statement"); (ii) a
specimen certificate representing the Common Stock; (iii) the form of proposed
Warrant Agreement between the Company and the Warrant Agent, including the form
of Warrant Certificate (the "Warrant Agreement"), governing the Warrants; (iv)
the Certificate of Incorporation of the Company, as presently in effect; (v) the
By-Laws of the Company, as presently in effect; (vi) the form of proposed
Contribution Agreement between and among GB Holdings, Inc., the Company, Greate
Bay Hotel and Casino, Inc. and Ace LLC; (vii) the form of the proposed Merger
Agreement among GB Holdings, Inc., GB Property Funding, Inc. and Greate Bay
Hotel and Casino, Inc.; and (viii) 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, when the
Registration Statement becomes effective and the Warrant Agreement has been duly
executed and delivered:

         1.   The issuance and sale of the Securities will have been duly
              authorized;

         2.   To the extent issued on the date the Registration Statement
              becomes effective, the Shares will have been validly issued, fully
              paid and nonassessable, and when issued in accordance with the
              terms of the Warrants, will be validly issued, fully paid and
              nonassessable; and

         3.   The Warrants, when duly executed, authenticated and delivered
              pursuant to the terms of the Warrant Agreement, 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.

         Our opinion expressed above is limited to 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. 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,

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

Gentlemen:

         We have acted as special regulatory counsel on gaming matters in the

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 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

               (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

documents of all documents submitted to us as certified, conformed or

         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.

consents, or approvals of the Commission which may be required in connection
with the consummation of the transactions contemplated by the Registration
Statements.

         (b) In acting as special gaming counsel for the Companies, we have
represented them on specific matters referred to us from time to time, but we
have not represented the Companies generally. We have made no independent
investigation of their files, nor have we made independent inquiries in
connection with this opinion as to factual matters.

         (c) We do not hold ourselves as experts in and express no opinion as to
the laws of any state or jurisdiction other than the laws of the State of New
Jersey. In rendering the opinions set forth herein, the scope of our review has
been limited to our review of the New Jersey Casino Control Act and the
regulations thereunder.

         (d) Our opinions set forth herein are based and rely upon the current
state of the law, and in all respects are subject to and may be limited by new
legislation and Commission regulations, as well as by developing administrative
and case law.

         (e) We assume no obligation to update or supplement our opinions set
forth herein to reflect any facts or circumstances that may hereafter come to
our attention or any changes in laws that may hereafter occur.

         (f) This letter is limited to the matters stated herein and no opinion
is implied or may be inferred beyond the matters stated. This letter is solely
for your benefit in connection
