I loved the Mt. Lebanon location and I love the downtown location. This place is a true gem and I don't believe until the new culinary renaissance (there, I said it) in Pittsburgh, did a place like II Pizzaiolo get the attention and growth it truly deserved.
They have so many fresh pastas and at prices that make sense. Also, the downtown location has outdoor seating that makes Market Square sparkle like a Lower East Side cafe. If you haven't experienced the new vibe that is budding in Market Square, then you're totally missing out. Get out of the "east end only" mentality and make your way back downtown, to the south, etc.
