Charlie's Burgers
Prospective diners who want to experience a Charlie’s Burgers dinner must first apply for an invitation, a process that involves filling out a survey about their interest in food. If they’re lucky, they’ll then be sent an e-vite to the next Charlie’s Burgers event. Neither the identity of “Charlie” nor the location of the event is disclosed, however; rather, on the evening of the dinner, invited guests are directed to a public spot—such as a newspaper box—to pick up directions.
Sounds like fun.
