Went to Ono last night (in the Hotel Gansevoort). I thought the staff was very accomodating and attentive (albeit was a Monday night). We got a sample of sushi, each with an accompanying sauce on top. My fave was the tuna with peanut sauce and a bit of crunch.
We also got the Tuna skewer. It was fine - nothing special.
Overall, food was good, but not so worth the prices. You are obviously paying for the fact that you are eating in the Meatpacking District.
