Don't be fooled by the shady looking strip mall area that looks ripe for gang activity at night. This place is a gem. They definitely are in the low rent district on the Sahara side of the strip and is Korean (not Japanese) owned. They do a great job in providing good sushi (even though they are far from the ocean) and their preparation and presentation are very good. This rivals some of the best Japanese restaurants on the strip without the high price. We had the tatami room with a party of 11 and the service was friendly and attentive. They even gave us a ride back to our hotel in their own cars....what service.
Their teriyaki meats aren't very good, but their yakitori is excellent, don't know why that is. Top picks also include sushi, sashimi, udon, unagi, agedashi tofu, gyoza, chawanmushi, and chirashi. Somebody was trained well in Los Angeles (where the owners are from.) Give it a try, you won't be dissappointed.
