We went on a Friday night. The waitress explained the restaurant as a fusion between Japanese and a Wisconsin tavern.
If 3.5 stars were an option that is what I would give them.
I ordered a Toyko Mule which had so much ginger I could barely drink it. We decided to split some dishes. First we ordered the gyoza. The pork dumplings were okay. They had a lot of fluid in them which made them virtually impossible to eat with chopsticks. I dropped one of mine on the table but ate it anyways. Next we ordered the TKO sushi roll. It had bacon, pineapple, avocado and seared tuna. It didn't taste bad but with Muramoto around the corner you have to do better. Next up was a pork belly skewer. Dry and boring. Finally we got the Udon XO which was the best dish of the night. It was flavorful and tasted like great lo mein.
The service was pretty decent considering how new they are.
Worth a second try but they need to up their game if they are going to survive on the square.
