California Code, Business and Professions Code - BPC § 24042.5

Notwithstanding any other provision of this division, any licensee under an on-sale general or on-sale general license for seasonal business who has a premises with a fixed counter or service bar in one room of the premises for the service of distilled spirits to members of the public for consumption on the premises and who has other rooms on the premises which can be utilized for the same purposes by means of a portable bar counter may elect to request the department to license the portable bar counter itself rather than the additional rooms as provided in Section 24042.  However, if two or more portable bar counters are utilized at the same time, in the same room, only one portable bar shall be required to be licensed.  The licensee shall pay to the department at the time of the application for each portable bar counter an amount equal to the license fee payable for a like period for the distilled spirits privileges of the original on-sale general license or on-sale general license for seasonal business.  Failure to obtain the portable bar counter license 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 pay the annual fees therefor.
