Sushi Mon have become our default sushi place. We always do ayce lunch and order a lot of nigiris. The fish were as fresh as you could hope for here in vegas -- comparable to goyemon (another favorite sushi place). Their rolls were good though none stands out -- but they will make you custom rolls which is great! Aside from our usual nigiris: super white tuna, yellow tail, salmon, eel, red snapper; we always order: frying jason, volcano, dragon roll, mussels, orgasmic salad and whatever else is on the daily special board. They have a more extensive (with grilled fish) dinner menu so its also worth going there for dinner but 808 sushi offers more grilled fish than sushi mon so thats where we go if we feel like having sushi/grilled fish for dinner.
Sushi Mon's service was great and friendly. We get our orders without noticing how long it has been... And we order a lot to get our money's worth! The flow of food coming our way was exceptional and they always refill our teas. The place is small enough that wait staff always see you if you're trying to get their attention.
One thing i will always come back here for is their lychee sherbet!!! There's not a lot of restaurants here that serve lychee sherbet... its always worth the drive to have a little of this treat!
