Item 3.01.     Notice of Delisting or Failure to Satisfy a Continued Listing
               Rule or Standard; Transfer of Listing.

On May 17, 2005, Grill Concepts, Inc. received a notification letter from the
NASDAQ Stock Market that the company is not in compliance with conditions for
the continued listing of the company's common stock on Nasdaq under NASD
Marketplace Rule 4310(c)(14) because the company has not filed its Quarterly
Report on Form 10-Q for the period ended March 27, 2005.

As previously announced, the company had delayed the filing of its Form 10-K
while it resolved certain lease accounting and other issues.  As a result of the
delinquency in filing the Form 10-K, the company was unable to complete and file
its March 27, 2005 Form 10-Q by the scheduled due date.  Further, the fifth
character "E" was appended to the company's trading symbol until the company
comes into compliance with the Nasdaq rules, changing the company's trading
symbol from GRIL to GRILE.  The company attended a hearing on May 19, 2005
before a Nasdaq panel regarding compliance with the listing standards.  Pending
a determination by the hearing panel, the delisting of the company's common
stock has been stayed and the company's common stock continues to trade under
the symbol GRILE.

Pursuant to the notification letter, Nasdaq advised that the delinquency with
respect to the March 27, 2005 Form 10-Q would be considered at the scheduled May
19, 2005 hearing of a Nasdaq Listing Qualifications Panel in rendering a
determination regarding the company's continued listing on Nasdaq.

The company filed its Form 10-K on May 23, 2005 and is working diligently to
complete and file its Form 10-Q.

On May 24, 2005, the company issued a press release announcing the receipt of
the notice from Nasdaq. A copy of the press release is attached hereto as
Exhibit 99.1.

Item 9.01.     Financial Statements and Exhibits.

Registrant has duly caused this Report to be signed on its behalf by the
undersigned hereunto duly authorized.
