Ever since a visit by Obama, this has really become THE tourist place to go for breakfast in Pittsburgh. It was already a long standing fixture, but definitely got pushed over the top by the executive visit a few years ago. As such, if you're not there before 9am on any given day, you could easily be standing in a line running down the street. Is it worth it? The place underneath all the tourist hype is a good old fashioned corner diner, with huge pancakes, black coffee and lots of fried meats. The place is very retro looking (original decor) which I like. Service was efficient, but definitely not friendly. If you can get there early enough, give it a try.
