When someone calls a bar the best in the world, you take notice — and when that person is as well traveled as Roger Ebert, it carries even more weight. Despite the high praise, however, The Old Town Ale House isn't known for its fantastic cocktails, or its great beer selection. Instead, this classic dive bar is all about atmosphere. Risque paintings of politicians in various states of undress line the walls, created by regular Bruce Elliott. A funky smell lingers. The drinks are cheap. With a history that dates back to the '50s and regulars that have been drinking there for nearly as long, it's an experience not to be missed — and it's location directly across from the Second City doesn't hurt, either.
