San Francisco's street food craze is moving indoors.
The "booze cart" brings the drinks and the bartender to your table in the Fifth Floor lounge.
The fully stocked cart moves around the floor looking for its next victim so by the time you your glass is empty, chances are your favorite purveyor of booze will be right back at your table.
