Stopped by here today since it's on the list of "must see" places in Pittsburgh. I ordered the world famous "Pitts-burger." It's unlike most other burgers in that French fries and cole slaw are placed on top of the meat in the sandwich. I e never had anything like that before.
It's definitely unique and worth a try. I didn't really like the sandwich that much but it's unique and the service was really polite and fast. It's a "must see" place while in Pittsburgh!
