I went here while staying at the Westin on business. The service was pretty good but the prices were outrageous: $15 for a hand roll!?! Moreover $45 for the chef's choice sushi dinner for only 12 pc was steep - especially when they charge extra for the miso soup. If the fish was fresh, I might have felt a little better about the prices.
I left $100 poorer and still hungry - won't be going back on my next trip! I can see why there were only 3 other people in the restaurant.
