CLUB SANDWICH: Andre’s after-dark empire just keeps expanding. The pint-sized entrepreneur disclosed Monday night at the presentation for House of Waris that he’s taken over a hotel next to the Cafe Flore on the Left Bank of Paris. Vincent Darre will be behind the decor. “We’re going for an old Seventies vibe. It’s going to be really private, as there are only around four big rooms, as well as a small bar,” said Andre, adding that the bar should be up and running within three weeks.
