                                  SCHEDULE 13D

Item 1.  Security and Issuer

         This Amendment No.3 to Schedule 13D, which was filed with the
Securities and Exchange Commission (the "SEC") on May 6, 2002, as amended on May
21, 2002 and June 17, 2002, relates to the common shares, $.01 par value (the
"Shares"), of Morton's Restaurant Group, Inc., a Delaware corporation (the
"Issuer"). The address of the principal executive offices of the Issuer is 3333
New Hyde Park Road, New Hyde Park, New York 11042.


Item 4.           Purpose of Transaction

         Item 4 is hereby amended to add:

         On June 18, 2002, High River and Porterhouse Acquisition Corp.
("Porterhouse"), a wholly-owned subsidiary of High River, delivered to the
Issuer an amended Agreement and Plan of Merger (the "Amended Agreement") by and
among High River, Porterhouse and the Issuer. The Amended Agreement provides for
merger consideration of $15.00 per share in cash for each outstanding share of
the Issuer as opposed to Castle Harlan's merger consideration of $13.50 per
share in cash. The Amended Agreement, which is in form substantially similar to

Porterhouse into the Issuer. A cover letter transmitting the Amended Agreement
is attached hereto as Exhibit 1 and incorporated herein in its entirety.

arrangements, understandings or relationships (legal or otherwise) with any
person with respect to any securities of the Issuer, including but not limited
to the transfer or voting of any of the securities, finder's fees, joint
ventures, loan or option arrangements, puts or calls, guarantees of profits,
division of profits or losses, or the giving or withholding of proxies.


Item 7.           Material to be Filed as Exhibits

1.       Letter to Richards, Layton & Finger, P.A. dated June 18, 2002.

            Re:   Morton's Restaurant Group, Inc.

Dear Steve:

I am pleased to transmit to Morton's Restaurant Group, Inc. through you the
Agreement and Plan of Merger By and Among High River Limited Partnership,
Porterhouse Acquisition Corp. and Morton's Restaurant Group, Inc., which has
been executed by High River Limited Partnership and Porterhouse Acquisition
Corp. on the understanding that it has been executed assuming that when executed
by Morton's the disclosure letter that it attaches to it will in form and
substance be identical to the disclosure letter dated June , 2002 which you sent
to me on June 9, 2002, and which was compared on June 8, 2002, to the extant
disclosure letter referred to in the CH-M Agreement. The enclosed Agreement is
undated but you are authorized to date it the date on which it is executed by
Morton's.

The only changes from the document which I sent you on June 14, 2002, are
exactly the same changes which were made by Morton's and Morton's Holdings, Inc.
in their Amendment No. 1 to Merger Agreement dated as of June 15, 2002. However,
as you are aware High River's merger consideration is $15 per share as opposed
to the $13.50 being paid by Morton's Holdings, Inc.


We understand that the Board of Directors will be required to determine whether
the High River

                                       -4-




proposal is a Superior Proposal. Please advise me by the close of business on
Thursday, June 20, 2002, that the Board has made the determination that the High
River proposal is a Superior Proposal or High River reserves the right to
thereafter give you written notice that it is withdrawing its High River
proposal and that, if it does so, it can and will no longer be bound to the
Agreement and Plan of Merger which I am enclosing herewith.

                                                              Very truly yours,

                                                                /s/ Marc Weitzen
                                                                    Marc Weitzen
