                                                              September 26, 2000

Special Committee of the Board of Directors
Rainforest Cafe, Inc.
720 South Fifth Street
Hopkins, MN 55343

Members of the Special Committee:

     You have requested our opinion as to the fairness, from a financial point
of view, to the holders (other than Landry's Seafood Restaurants, Inc. and its
affiliates) of common stock of Rainforest Cafe, Inc. (the "Company") of the
consideration to be received by holders of common stock in the Transaction
described below, pursuant to an Agreement and Plan of Merger to be dated as of
September 26, 2000 (the "Agreement"), among the Company, Landry's Seafood
Restaurants, Inc. ("Landry's") and LSR Acquisition Corp. ("Acquisition"), a
wholly owned subsidiary of Landry's. The Agreement provides for the commencement
by Landry's of a tender offer (the "Tender Offer") to purchase shares of Company
common stock outstanding at a price of $3.25 per share, net to seller in cash
(the "Offer Price") and the subsequent merger (the "Merger") of Acquisition into
the Company in which the remaining shares of Company common stock will be
converted and exchanged for cash equal to the Offer Price. The Tender Offer and
the Merger are collectively referred to as the "Transaction." The terms and
conditions of the Transaction are more fully set forth in the Agreement.

     U.S. Bancorp Piper Jaffray Inc., as a customary part of its investment
banking business, is engaged in the valuation of businesses and their securities
in connection with mergers and acquisitions, underwriting and secondary
distributions of securities, private placements and valuations for estate,
corporate and other purposes. We will receive a fee for providing this opinion.
This opinion fee is not contingent upon the consummation of the Transaction. The
Company has also agreed to indemnify us against certain liabilities in
connection with our services. U.S. Bancorp Piper Jaffray Inc. is entitled to an
additional fee in the event of consummation of the Transaction. In the ordinary
course of our business, we and our affiliates may actively trade securities of
the Company for our own account or the account of our customers and,
accordingly, may at any time hold a long or short position in such securities.

     In arriving at our opinion, we have undertaken such review, analyses and
inquiries as we deemed necessary and appropriate under the circumstances. Among
other things, we have reviewed (i) the draft dated September 18, 2000 of the
Agreement, (ii) certain publicly available financial, operating and business
information related to the Company, (iii) certain internal financial information
of the Company prepared for financial planning purposes and furnished by the
management of the Company, (iv) certain publicly available market and securities
data of the Company, and (v) to the extent publicly available, financial terms
of certain acquisition transactions involving companies operating in industries
deemed similar to that in which the Company operates and financial data of
selected public companies deemed comparable to Company. We had discussions with
members of the management of the Company concerning the financial condition,
current operating results and business outlook for both the Company on a
stand-alone basis and the combined company resulting from the Transaction.

     We have relied upon and assumed the accuracy, completeness and fairness of
the financial statements and other information provided to us by the Company or
otherwise made available to us, and have not assumed responsibility for the
independent verification of such information. We have relied upon the assurances
of the management of the Company that the information provided to us as set
forth above by the Company has been prepared on a reasonable basis, and, with
respect to financial planning data and other business outlook information,
reflects the best currently available estimates, and that they are not aware of
any information or facts that would make the information provided to us
incomplete or misleading. Without limiting the generality of the foregoing, for
the purpose of this opinion, we have assumed that the Company is not a party to
or contemplating any material pending transaction, including external financing,
recapitaliza-

tions, acquisitions or merger discussions, other than the Transaction, a
voluntary reorganization under applicable bankruptcy laws and related store
restructuring, or in the ordinary course of business.

     We have also assumed that the Transaction will be taxable for federal
income tax purposes to the holders of Company common stock. In addition, in
arriving at our opinion, we have assumed that, in the course of obtaining the
necessary regulatory approvals for the Transaction, no restrictions, including
any divestiture requirements, will be imposed that would have a material adverse
effect on the contemplated benefits of the Transaction.

     In arriving at our opinion, we have not performed any appraisals or
valuations of any specific assets or liabilities of the Company and have not
been furnished with any such appraisals or valuations. We express no opinion
regarding the liquidation value of any entity. Without limiting the generality
of the foregoing, we have undertaken no independent analysis of any owned or
leased real estate, or any pending or threatened litigation, possible unasserted
claims or other contingent liabilities, to which the Company or its respective
affiliates are a party or may be subject and our opinion makes no assumption
concerning and therefore does not consider the possible assertion of claims,
outcomes or damages arising out of any such matters.

     This opinion is necessarily based upon the information available to us and
facts and circumstances as they exist and are subject to evaluation on the date
hereof; events occurring after the date hereof could materially affect the
assumptions used in preparing this opinion. We are not expressing any opinion
herein as to the price at which shares of Company common stock have traded or
may trade at any future time. We have not undertaken to reaffirm or revise this
opinion or otherwise comment upon any events occurring after the date hereof and
do not have any obligation to update, revise or reaffirm this opinion, except as
expressly provided in our engagement letter with you.

     This opinion is directed to the Special Committee of Board of Directors of
the Company and is not intended to be and does not constitute a recommendation
to any stockholder of the Company regarding whether to tender shares of common
stock in the Tender Offer or how to vote in the Merger. We have not been
authorized by the Special Committee of the Board of Directors of the Company to
solicit other purchasers for the Company or alternative transactions to the
Transaction. We were not requested to opine as to, and this opinion does not
address, the basic business decision to proceed with or effect the Transaction.
This opinion shall not be published or otherwise used, nor shall any public
references to us be made without our prior written approval. However,
notwithstanding the foregoing, we consent to inclusion of this opinion in the
Schedule 14D-9 relating to the Tender Offer and the proxy statement relating to
the Merger, in accordance with the terms of our engagement by the Company.

     Our opinion addresses solely the fairness of the Offer Price to be paid in
the Transaction and does not address any other term or agreement relating to the
Transaction, or the ability of Landry's to finance or otherwise successfully
consummate the Transaction.

     Based upon and subject to the foregoing and based upon such other factors
as we consider relevant, it is our opinion that the Offer Price proposed to be
paid in the Transaction pursuant to the Agreement for the common stock of the
Company is fair, from a financial point of view, to the holders of common stock
of the Company (other than Landry's or its affiliates) as of the date hereof.

                                            Sincerely,

                                            U.S. BANCORP PIPER JAFFRAY INC.

                                       A-2
