ITEM 1.     SECURITY AND ISSUER

     This statement on Schedule 13D relates to the Common Stock, $0.01 par value
(the "Common Stock"), of Famous Dave's of America, Inc. (the "Issuer"). The
Issuer's principal executive office is located at 12701 Whitewater Drive, Suite
200, Minnetonka, MN 55343. This Statement on Schedule 13D amends the Statement
on Schedule 13G relating to the Common Stock filed by the Reporting Persons (as
defined below) on August 12, 2005, as amended by Amendment No. 1 filed on
February 14, 2006.


ITEM 2.    IDENTITY AND BACKGROUND.

     This Statement is being filed by each of the following persons (the
"Reporting Persons") pursuant to Rule 13d-1(k) promulgated by the Securities and
Exchange Commission (the "Commission") pursuant to Section 13 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"): Vicuna Advisors LLC, a
Delaware limited liability company ("Advisors"), Vicuna Partners LLC, a Delaware
limited liability company ("Partners"), and Joshua G. Welch ("Welch").

     Partners is the general partner of, and Advisors is the investment adviser
to, investment partnerships that own the Common Stock. Welch is the sole
Managing Member of Partners and Advisors.

     The filing of this statement is not an admission by any Reporting Person
that such Reporting Person and any other Reporting Person or any other person
constitute a "group" for purposes of Section 13(d)(3) of the Exchange Act or
Rule 13d-5 thereunder or that any Reporting Person is the beneficial owner of
any securities owned by any other Reporting Person or any other person.

     The principal business of Partners is to act as general partner of
investment partnerships organized to make investments in common and preferred
stock and other interests in business organizations, domestic or foreign, with
the principal objective of appreciation of capital invested. The principal
business of Advisors is to provide portfolio management services to such
partnerships and other domestic and foreign investment entities. The address of
the principal business and principal office of each of the Reporting Persons is
c/o Vicuna Advisors LLC, 230 Park Avenue, 7th Floor, New York, New York 10169.

     During the past five years, none of the Reporting Persons has been
convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors). During the past five years, none of the Reporting Persons was a
party to a civil proceeding of a judicial or administrative body of competent
jurisdiction as a result of which such person was or is subject to a judgment,
decree or final order enjoining future violations of, or prohibiting or
mandating activities subject to, federal or state securities laws or finding any
violation with respect to such laws.

     Mr. Welch is a United States citizen.


ITEM 3.   SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

     The source of funds used to purchase the shares of Common Stock owned by
the Reporting Persons (the "Shares") was working capital of investment
partnerships for which Master acts as general partner and Advisors acts as
investment adviser. The aggregate amount of such funds was $5,374,405.


ITEM 4.   PURPOSE OF TRANSACTION.

     The Shares were acquired in the ordinary course of business for investment
purposes. The Reporting Persons' intention was to review their investment in the
Issuer on a continuing basis and, depending upon price and availability of
securities of the Issuer, subsequent developments affecting the Issuer, the
Issuer's business and prospects, general stock market and economic conditions,
tax considerations and other factors deemed relevant, to consider increasing or
decreasing the size of their investment in the Issuer.

     On March 20, 2006, Joshua G. Welch, Managing Member of Advisors, wrote to
Dean Riesen, Director and Chairman of the Nominating Committee of the Issuer's
Board of Directors, proposing that a representative of Advisors be added as a




                                       5



member of the Board of Directors of the Issuer in the interest of representing
the Reporting Persons' partners and all shareholders of the Issuer. The letter
stated that the representative will bring to the Issuer's Board of Directors a
body of knowledge informed by frequent, close contact with multi-unit restaurant
operators, and, most importantly, an owner's perspective stemming from the
Reporting Persons' shareholding in Famous Dave's.

     The Reporting Persons may take a number of actions in connection with their
proposal of a representative of Advisors as a director. They may communicate and
discuss their views with other shareholders of the Issuer and members of the
management and Board of Directors of the Issuer. In the future, the Reporting
Persons may decide to purchase additional shares of the Common Stock, or sell
part or all of their current holdings of Common Stock. The Reporting Persons
reserve the right to exercise any and all of their respective rights as
shareholders of the Issuer in a manner consistent with their equity interests.

     Except as set forth above, none of the Reporting Persons has any present
plans or intentions which relate to or would result in: (i) the acquisition by
any person of any additional securities of the Issuer, or the disposition of
securities of the Issuer; (ii) an extraordinary corporate transaction, such as a
merger, reorganization or liquidation, involving the Issuer or any of its
subsidiaries; (iii) the sale or transfer of a material amount of assets of the
Issuer or any of its subsidiaries; (iv) any change in the present board of
directors or management of the Issuer, including any plans or proposals to
change the number or term of directors or to fill any existing vacancies on the
board; (v) any material change in the present capitalization or dividend policy
of the Issuer; (vi) any other material change in the Issuer's business or
corporate structure; (vii) any other material change in the Issuer's business or
corporate structure; (viii) changes in the Issuer's charter, bylaws or
instruments corresponding thereto or other actions which may impede the
acquisition of control of the Issuer by any person; (viii) causing a class of
securities of the Issuer to be delisted from a national securities exchange or
to cease to be authorized to be quoted in an inter-dealer quotation system of a
registered national securities association; (ix) a class of equity security of
the Issuer becoming eligible for termination of registration pursuant to Section
12(g)(4) of the Securities Exchange Act of 1934; or (xi) any action similar to
any of those enumerated above.

general partner and Advisors acts as investment adviser are the beneficial
