My wife and I "dined" there tonight. We were immediately seated. Our waitress Nika(?) took our drink order and our sushi menu. No problem there. I always order filet, shrimp, and scallops at any Japanese restaurant that I go to. If it is not on the menu, it is a small upcharge. I asked our waitress about the upcharge and she said she would ask. 10 minutes later she asks for our order. I AGAIN ask her about the upcharge and she vanishes again. She appears after some time and says that it would be a $1 upcharge from the standard steak. No problem. Sushi was delivered. Average to slightly below average quality. Table chef was very good although they skimp on the fried rice. He cooked well and engaged the other diners. Now for the check. It was brought out. She overcharged us for the meals and charged us for an extra beverage. We called her attention to it and she hurried off. At this point everyone else at the table has left. Another group is seated at an adjacent table. We ask that waiter to check on our waitress. Several minutes later they send a front-house worker to us to explain that our waitress was new and that the upcharge would be $2 per person and they COULD NOT change that. Really? She gives us the bill. The extra beverage is still on there. We brought it to her attention. She hurries off. 15 minutes more elapse. Finally, a female manager comes to us. She gives us the check, apologizes again, and says that they CANNOT change the upcharge. They are adamant about a total of $2. Ridiculous! We just took it out of the gratuity. We will NOT be going to Sumo again. There are FAR better places not too far away. Go here if you wish to spend your money on bad service and lots of excuses.
