When our Japanese friends lived in the St. Louis area they introduced us to this restaurant and said it was the most authentic Japanese food here. The sushi is amazing! Although our friends have moved back to Japan, we frequently dine here. We have tried many of the sushi rolls, but always get the Lake St. Louis roll, Rainbow Roll, and Akashiro roll. The red tuna nigiri is delicious (slice of raw red tuna on rice). The miso soup is a great way to start your dining experience. When we introduce friends and family to Sushi Sen, they always declare it was the best they have ever had and return on their own. We highly recommend this delicious and authentic restaurant!
