Billy Goat Tavern, Chicago

Descend the murky stairs and "Butt on in" as the sign says. Made famous by John Belushi's "Cheeseborger, cheeseborger, cheeseborger" Saturday Night Live skit, the Billy Goat Tavern never fails to please in all of its sleazy glory. For a truly authentic experience, enter late when all the tourists have left. Check out the old Mike Royko columns and photographs on the walls. For lunch and dinner you can order a hotdog, a ham and cheese or a "cheeseborger," but you cannot order fries, only chips. Try the "Doublacheez" for a wallop.
