Prince’s Kitchen used to be one of my favourite for Teppanyaki, used to be buffet style available at a reasonable cost. The Korean bbq place at Galleria also has teppanyaki and good quality beef in a buffet, the teppanyaki style is around 150?rmb I think. There’s also one across from the HSBC in Tongzilin, a little expensive, 1st floor – can’t remember the name or be more descriptive though..
