Any day now, Joe Germanotta will debut Joanne, an Italian restaurant on the Upper West Side, and it's likely his devoted daughter (Lady Gaga) will be dropping by. We can't guarantee you'll see Hugh Jackman or Justin Timberlake at the places they co-own in the City, but, then again, you never know. Celebrities are a common sight at durable hotspot The Spotted Pig since investors include Bono, Jay-Z and Michael Stipe. Other long-running venues backed by stars include Nobu (Robert De Niro), Do Hwa (Quentin Tarantino), P.J. Clarke's (Timothy Hutton) and The Waverly Inn (Graydon Carter). See our slideshow for other celebrity-owned ventures that aspire to such staying power.
