I've eaten here for lunch and dinner, both during two different groups of restaurants and it was delicious every time! It's fun to go with adventurous friends who are down to share a few things from each kitchen so you can try them all. The concept is very cool and fits right in in Pittsburgh.
The atmosphere is kind of noisy and hectic- very enjoyable, but definitely more of a casual meal out with friends than a quiet date kind of place.
It can be a little confusing on your first visit to know how things work... You order and pay separately at each kitchen and get a number card so they can bring your food out to you, seat yourself anywhere, and grab plates and flatware from the various stacks around the seating areas. :)
