Call it mafioso culinary tourism. If you've ever wanted to tour the nation's mob-connected eateries -- savoring both the food and the murderlicious vibe -- this is your guide. Of course, Vegas is the on menu. From the Huffington Post:

To catch some present-day gangster action, ultra-exclusive Rao's and scene-of-the-crime Sparks Steak House are the usual suspects, while Chicago's Green Mill takes you back to Al Capone's heyday. Instead of a fedora and pin-stripe suit, these days goodfellas are more likely to be juiceheads that look something like Café Martorano's owner, nephew of former South Philly mobster "Long John" Martorano, although he chose the culinary life over La Cosa Nostra.

Many of the mobster restaurants are a real slice of Americana. History buffs gravitate towards places like Campisi's in Dallas, where mob-affiliated Jack Ruby, Lee Harvey Oswald's hit man, was known to hang out, and hipsters can check out a real speakeasy in Providence, R.I. -- Camille's which has seen many a famous face, whether a made man or a Hollywood leading man.
