There's this restaurant sa SM Sucat. Ersan/Erhao.. Im not really sure of the name.
But it is a taiwanese restaurant and I tried their noodles with seafood dimsum. The dimsum was amazing. It is also quite affordable. I don't know how much it is if you order it as a stand alone. But the noodles with seafood dimsum is around 170 pesos. They have a large size that can feed 2 or 3 (depends on your appetite) for less than 300.
