Cityfile: New York's Most Notable and Influential

It's never a good sign when a club closes down and no one notices (or cares), nor is it especially encouraging that a venue that once boasted about its long list of celebrity investors is forced to announce the news with a homemade sign taped to the door. It isn't clear why The Plumm closed its doors a few days ago. (Some sort of "legal problem," apparently.) But if it falling off the radar screen a few years ago has led to financial problems, co-owner Noel Ashman might want to take a page from Nikki Beach in Midtown, which seems to have come up with a surefire way to stay alive during the economic downturn: It's now hosting swinger parties for "sexy couples" and single women. Be advised, gentlemen: No leather pants with unbuttoned silk shirts, please.

There's probably been a time or two when you've been tempted to check out a restaurant or bar simply because some celebrity supposedly "owns" it. Maybe I'll see Justin Timberlake devouring a plate of ribs at Southern Hospitality! Or I'll spot Robert De Niro slurping on some pasta at Ago! Restaurateurs know this, too, of course, which is why they're all so eager to attach a celebrity name—any one will do!—to their ill-conceived bistro, brasserie, speakeasy, lounge, or barbecue shack. We don't want to be the ones to crush your dreams and tell you that there's no chance you'll see these famous faces at these venues. Just in case you're the more optimistic type—or just curious who has a stake in what—we happily introduce the Cityfile celebrity-owned restaurant/bar map!
