Two words: sushi pizza. One of the best things I've had in Pittsburgh--and I had it delivered, so I imagine it's even better when it's more fresh in the restaurant.
Before you go cringing at those two words going together--it's a slightly crispy scallion pancake topped with seaweed salad, raw tuna, raw salmon, avocado and spicy mayo. Amazing. I ordered a few other rolls as well, and they were good, but the sushi pizza stole the show. I'll definitely be ordering again, and hopefully going to the restaurant itself.
