I'm not a fan of all you can eat Asian food, because I know the quality isn't there. I'd much prefer quality over quantity when talking about food. I must say though sushi mon is legit. They make all the sushi fresh to order. You just tell the waitress or sushi chef what you want and they make it right there. The variety of different sashimi / sushi rolls / appetizers makes this place well worth the $26.95 for dinner.
There are some sashimi's that you can only order just one per person because of how expensive it is, but at least you get to try it still.
The people working there were really nice. It wasn't too busy, but I herd when it gets busy that the food takes awhile to come out. You have to make sure that you eat all your food along with the rice or else you'll get charged extra.
I'll definitely come back to this place when I come back to Vegas!
