Kaizen always has prompt and friendly service and amazing food! There are at least 10 rolls on their menu that I love, and I'm pretty picky with which fish I will and won't eat. Their All-You-Can-Eat is a really good deal considering that it includes appetizers, specialty rolls, sashimi, dessert, and anything else that would ever be on a Japanese menu. Lunch prices for AYCE go until 4, and they also do it on weekends. Kaizen is my absolute favorite place to eat in Vegas!
