         Re:  Registration Statement on Form S-8

Ladies/Gentlemen:

         We are acting as corporate counsel to Buffalo Wild Wings, Inc. (the
"Company") in connection with the original registration by the Company on Form
S-8 (the "Registration Statement") under the Securities Act of 1933, as amended
(the "Act") of options and 1,292,962 shares (the "Shares") of Common Stock
issuable pursuant to the Company's 2003 Equity Incentive Plan and 2003 Employee
Purchase Plan (the "Plans").

         In acting as such counsel and for the purpose of rendering this
opinion, we have reviewed copies of the following, as presented to us by the
Company:

         1.       The Company's Articles of Incorporation, as amended.

         2.       The Company's Bylaws, as amended.

         3.       Certain corporate resolutions adopted by the Board of
                  Directors and shareholders of the Company pertaining to the
                  adoption and approval of the Plans.

         4.       The Plans.

         5.       The Registration Statement.



         Based on, and subject to, the foregoing and upon representations and
information provided by the Company or its officers or directors, it is our
opinion as of this date that:

         1.       The Shares are validly authorized by the Company's Articles of
                  Incorporation, as amended.

         2.       Upon issuance and delivery of the Shares against receipt by
                  the Company of the consideration for the Shares pursuant to
                  the terms of the Plans, the Shares will be validly issued,
                  fully paid and nonassessable.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.

                                                Very truly yours,

                                                FREDRIKSON & BYRON, P.A.
