I've been here plenty of times and have never once completely ordered for myself. I love the cold milk tea but every time I try to order it, the waiter looks at me like I'm from outer space and my friend takes over for me in Chinese.
Aside from the language problem, food here is quite good. I've tried quite a variety of things but really enjoy their fried rice, beef in black bean sauce, and the stir fried snow pea leaves (I've never had this before until this restaurant).
We like being seated in a booth and usually can unless it's very busy.
Service, aside from my language problems with the milk tea, is pretty good. They bring food out quickly, replace tea quickly and always ask how things are (I'm assuming... they ask in Chinese to my friend). You do need to waive down someone to get the bill but that too comes quickly and things are pretty cheap.
