(a) Any licensee under an on-sale general license or an on-sale general license for seasonal business who maintains upon or within the premises for which the license is issued more than one room in which there is regularly maintained a fixed counter or service bar at which distilled spirits are served to members of the public for consumption within the licensed premises shall obtain from the department, and the department may upon request issue, a duplicate of the original license for each room, in excess of one, containing a fixed counter or service bar and shall post a duplicate of the original license in each room. Failure to obtain the duplicate licenses and to pay the fees, as specified in Section 23320, shall subject the licensee to the penalties imposed by this division for failure to obtain an original license or to pay the annual fees therefor.

(b) The duplicate license may be issued to a room reserved for the exclusive use of designated patrons, provided that the department shall, in the event the license is issued, endorse upon the license the terms and conditions under which the privileges conferred by the said license may be exercised, and provided further that upon the receipt by the department of the request for the duplicate license written notice thereof which shall consist of a copy of the request shall immediately be mailed by the department to the sheriff or chief of police within whose jurisdiction the premises are situated and no duplicate license shall be issued by the department until at least 30 days after such mailing. Upon receipt by the department within 30 days of a protest by the sheriff or chief of police within whose jurisdiction the premises are situated, the department shall not issue the duplicate license until after a hearing is held by the department within the county or city affected and said hearing shall be conducted in accordance with Chapter 5 (commencing with Section 11500), Part 1, Division 3, Title 2 of the Government Code and the department shall have all the powers granted therein.
