By far the best sushi in the US we have had so far!
Every time we come to Vegas we rent a car and make the trip to Sushi Mon. We get the All-U-Can-Eat and we take full advantage of it. Everything we had was delicious, fresh, and wonderful!
I wish I could be more specific but we had so much that we can't remember it all. Be sure to get there early in the day to make a reservation, the AYCE availability fills up fast at night.
The sushi chefs are very nice and the wait staff is great too! Be sure to order half orders (4 pieces) so you can try a lot of different rolls.
Remember people, you have to eat the rice too! Don't get all you can eat and pick the fish off! And don't complain when they tell you that you have to eat the rice. If you don't like it then just order sashimi a la carte.
