I think this one is the best steamboat buffet for me so far, in term of value for money. For RM17.90 per person and RM12.90 for senior citizen (>55 years old), this restaurent located at the heart of the city, offers free flow of Dim Sum, Penang Char Koay Teow, Fried Lala, Ais Kacang, Chinese tea (with individual pot), Ice Cream and many others, in addition to the usual BBQ chicken and fishes, prawns, crab, mushrooms and various fish balls.

One good advise though, is to pick the only food that one likes, otherwise it is like a torture to the taste bud and stomach.
