Before a Class B license of any type may be issued, the applicant shall attest in a sworn statement that gross receipts from food sales in the restaurant will be more than the gross receipts from the sale of alcoholic beverages. If the license holder fails to maintain more gross receipts from the sale of food than gross receipts from the sale of alcoholic beverages for a 6–month period, the Board may revoke the license. Subject to paragraph (2) of this subsection, a license holder of a Class B license of any type shall file with the Board a sworn statement that the gross receipts from food sales in the restaurant for the 6–month period immediately before the filing of the report are more than the gross receipts from the sale of alcoholic beverages. The Board may require a license holder to provide: the sworn statement required under paragraph (1) of this subsection at least biannually, on dates to be set by the Board; and supporting data to establish that the requirements of paragraph (1) of this subsection have been met.
