Some like it tasteless? Well, then this is your address. Great selection of Chinese, Japanese and even some Thai cuisine which... doesn't taste like anything. I had a solo dinner and was glad that I didn't bring anyone along: I wouldn't recommend this for any other type of visit, certainly wouldn't envite wy spouse to this place. The principle of the place: you pay a fixed price and help yourself as much as you may consume. Some must be going to restaurants for the amount, not for the taste. In O-Sishi one can't complain about the quality: the food is fairly fresh and you probably won't get a poisoning. So why is it not scrumptious? Problem is, there is a feeling of a factory in this place, no setting, no atmosphere, no human touch, albeit a very correct service from the waiters. The food is not prepared here with a loving touch of a real chef. Most natural taste I could get was a steam-boiled rice from a machine. Caramelised chicken or beef has no taste, neither do shrimps of any form. Noodle stir fry is the only reason I didn't downrate this place completely. One part of the experience includes selecting your raw ingredients to be cooked in wok in front of you. This works, only not to the best result. Perhaps they didn't get their sauce right. Recommended only in case of extreme hunger.
