I've tired every sushi place around Hua Hin and several in BKK, but nothing comes close to the perfect sushi at Sakura. It is comparable to much of the food I ate in Japan. The owner is one of the nicest guys to run a restaurant in town and his prices can't be beat. Fantastic food, great location, without any of the gimmicky junk that is usually found in Thai sushi places.
I usually go there about twice a month, and have done so for the last 3+ years. I still find and try new things on his vast menu and I have never been disappointed.
