When we drive to Vegas, this is always the first stop before we hit the strip. Sometimes we even make Vegas trips just for Sushi Mon. Great quality cuts for the sushi, which is pretty much the only thing I order here. The service is exceptional too.
Never got the rolls so I can't review them, but going back to the sushi. The salmon cuts are very nice! They usually have 3-4 featured sushi, but it costs a little more, just charges you dinner prices which is about 3 bucks more. If it's available, it's kind of a no brainer for me.
Love this place, highly recommend it, which I do to all my friends. There's dessert too, but it's up to you. I usually just eat more sushi instead, but the ice cream is great.
