This is good... that is the simplest most correct way of talking about Sushi Mon... scratch that this is REALLY good.
I was suggested this place by a friend and I have been back 4 times in 2 weeks (alright I do have a sushi problem). The fish here is fresh, the chefs have great suggestions as to new things to try and it is AYCE!!! I even drive down from North Las Vegas for this sushi.
I am a big Uni (sea urchin) fan and have been consistently impressed with the quality. My father (who used to go to Japan for business often) said that it was some of the best uni that he has had in the US. The problem is they do limit you. The other fish on the menu has consistantly been fresh and delicious. Don't be afraid to try new things along with the gold standards (yellowtail, tuna, salmon) as they are all good.
Like most of the AYCE sushi places I have been to you can order anything on the menu including appetizers and dessert. The menu is a good size with a nice variety of fish and rolls. Another positive is that if you are the only diner for AYCE you can order half rolls. This sushi place didn't try to fill me up on rice or give me a paper thin slice of fish. I would rate this sushi place high for the AYCE AND the sitdown sushi places.
I guess that they have another location but I haven't been there.
Seating can be rough but I haven't had to wait long... for even less time sit at the sushi bar.
