It's owned & operated by a Japanese man. The food is very good and authentic Japanese, but recently they changed the menu and prices have gone up in the new menu, which is quite sad. The portions are smaller in comparison to the prices, but the food tastes quite good. As soon as you are seated, they serve green tea; as for appetizers go I like their Agedashi tofu, kolokke and the fried tuna tempura in homemade teriyaki sauce is amazing! For main dishes I like their chicken katsu don or teriyaki don; I tried a pork dish cooked in ginger sauce, but that didn't go well for my taste, the meat was too fatty & chewy.
Anyway, they also have Japanese desserts like kakiage, which contains some shaved ice, with vanilla ice-cream, some fruit pieces like kiwi & strawberry, some sweet jelly, some sweet red bean paste and some kind of sweet gummy bits, perfect for a good summer day!
The service is not so great, since they don't have any servers or kitchen help, the owner is the only person cooking & serving most of the time. I guess being opposite to Kirin, is a disadvantage for them, because Kirin sucks most of the customers who feel like eating Japanese. As for me, I would prefer Rikka any day, instead of Kirin. Although they should get a liquor licence & serve some nice japanese sake or beer, that would go great with their food!
