We went to Japan this Spring - and this place is one of the closest 'Authentic Japanese' places we've found in Cleveland. A+ Salmon in all its sushi'esque forms, amazing Beef Tartar (Filet Mignon super rare with Ponzu sauce- Amazing!) - and the entry level basic sushi lunch entrees are delicious. Portions are slightly on the smaller side- but that's because in this case you're paying for Quality of Quantity. Havnt done their Happy Hour Yet, but i believe they have discounted appetizer and drink specials from 4-6.
Service is always fast, and its a great place to impress people without breaking the bank. Great Miso as well.
