I've only been there for Sunday brunch (many times), so I can't speak for their lunch or dinner, but this is by far the best brunch in Pittsburgh. It is a little on the expensive side ($26.95 per person), but the large variety they have makes the price worth it! From every breakfast food you could imagine (made to order pancakes, waffles, and omlettes) to the tastiest prime rib & seafood, to the amazing desserts!...this place has it all! However, you MUST save room for banana's foster, and of course a fresh donut that you can grab right out of the donut machine. Tip: if you want a mimosa ($4), they don't start serving them until 11am.
One downfall: they really cram you in there. The tables are way too close together with limited room to move, and not much privacy for conversation.
