the resturant u try, i think the chef is from mainland china, and the chef next to the Threater is from Hong Kong. And Hong Kong cooking is the same as Cantonese style.
So, it means, the first one maybe from North Area of China cooking style, while the other is from southern china (cantonese style)
Just like, Jacky chan is cantonese while Jet Li is mainland chinese people. Similar but not the same.
Actually, i want to ask how much u pay for your meal ?
