Proprietor: Danny DeVito

Location: South Beach, Florida, USA

Until Gary Busey invests in an ice-cream van from which to sells cones of hitherto unrecognised flavours to terrified children, our list of strange-but-true examples of Hollywood entrepreneurship is topped by Danny DeVito's South Beach chophouse. Not just one of Florida's most acclaimed dining rooms (regulars include Liza Minnelli and Timothy Hutton), it's a celebration of all things DeVito. Menu staples include Baked Clams Devito, Calamari Devito and Wagyu steak crusted in, er, Devito dust. And if that doesn't satisfy diners' DeVito cravings, there are 19 ginormous flat-screens showing his movies on continuous loop. Warning: Twins may cause indigestion.
