Love Health Vegetarian is a nice, small restaurant close to Sunway Giza Mall.
They offer a wide range of Chinese dishes, many of the with mock meat, fish or seafood.
The food is nice, but it can be hard to find what you want, as the menu (in English) simply gives very short descriptions of the available dishes and has only few images. If you know your way around the "Classical" Malaysian Chinese dishes, you will have much of a choice. If not, you might be better off meeting a local person here.
Cons: Heavy on mock meat/fish/seafood
