We went there as a group of 7 and booked reservation beforehand. The food came quickly, but the taste was mediocre for its price ($40 after tax and tips).
This is a sushi and dim-dum AYCE restaurant, but honestly if you want to try dim sum, just go to somewhere else in Chinatown. Also, there were not too many sashimi selection. One of the things I like is the salmon and tuna tataki.
Last but not least, the service was not good. The sever did not take the plates on time, probably because the restaurant was full. At the end, when we were about to pay and one of the waitress was cleaning up the table, she took a bowl and the soup in the bowl spilled my friend's pant. It is understandable as long as you apologize, but she didn't say anything and just give my friend some napkin. Eventually they didn't charge my friend's $5 tip, but this wasn't a pleasant experience.
