We've been there two times during our holidays in San Jose. What can I say, it's just amazing. Don't let the appearance of simple American-style take away fool you. The chief and the staff are doing outstanding job. They create real masterpieces. The place also have plenty of options for vegetarians (which is not usual in San Jose, believe me). Actually there are more options to choose from than I've ever seen in any Japanese restaurant. They can always make something else for you. And the food is not just extremely tasty, it's a sight for sore eyes! The prices are more than fare. Actually for such quality of food you might expect to pay more.
So if you can imagine an exquisite Japanese restaurant disguised as an ordinary sushi-shop, than that's it. When you visit such places and try food of such quality you want to come back again and again. It's a shame we live so far away that we hardly ever going to be in this part of Mexico again. But if we are I truly hope the place will still be there!
