For as many times as I've been in the downtown Pittsburgh and Market Square areas, I did not know this place existed until a group of friends came here for lunch following the St. Paddy's Day Parade.
It's a cozy greasy spoon type place with some very reasonably priced breakfast and lunch items. I ordered the loaded French toast, which included two slices of Italian bread with cream cheese and strawberries, for $6.
I have no idea how long this place has been here, but it seems pretty cool to have a cute lil diner in the middle of downtown. Service was good.
