If it were only about the sushi, Nobu would get 5 stars from me. But, I knock off 2 stars for service. We walked in on a Saturday night and got seats at the sushi bar, which is the place to be. We went with our sushi chef's suggestions, which were Nobu's house specialties, including \"new-style sashimi.\" These consist of the best fish, sashimi style, with delicate sauces and garnishes: yellowtail with jalapeno, live octopus with a Peruvian chili paste, whitefish and salmon with ponzu sauce, tuna with miso-mustard sauce. Everything was first-class, including the Junmai Daiginjo sake.\n\nThen, I ordered the bento box chocolate cake dessert. We were told it would take 8 minutes to cook. No problem - our bellies were happily full of sashimi. 20 minutes later, however, still no dessert, and we finally were able to flag someone down to check on it. Another ten minutes went by. Our waiter then came out to tell us there was a mixup in the kitchen and our cake went to another table. He tried to give us a plateful of mochi ice cream to tide us over - this didn't go over well, as the last thing we wanted was to eat a plateful of mochi ice cream and then a chocolate cake. Another ten minutes or so, the dessert came out. It was excellent, but frankly wasn't worth waiting over half an hour for. We ask ed for the check while still eating...took another ten minutes...gave the credit card and another ten minutes went by...waiter came out to tell us the credit card isn't clearing and do we want to give another card? By this point, well over an hour had gone by since dessert was ordered and we just wanted to leave already. \n\nWhen our check finally arrived, they did charge us for the dessert that took over 30 minutes to arrive at our table. When I mentioned this to the server, he took it right off the bill. But I was miffed that I even had to ask - the right thing to do would have been to take it off in the first place.\n\nToo bad, since up until we ordered dessert we were very pleased with the sushi our wonderful chef served us. Even for a Saturday night in Vegas, the service was unacceptably unresponsive for such a high-end restaurant.
