Big menu -- but inconsistent. Sometimes food is good here, sometimes it isn't. Sometimes some items are very good here -- sometimes they aren't.
One of the major differences between here and other local places is the dim sum. However, this is unimpressive and most of it is likely frozen as the flavor and texture don't resemble that of fresh dim sum at all. If ordering anything, I'd go for the noodle soups over other options as Lai Lai, Golden Wok, and others have better "wok hay" in my opinion.
Prices are reasonable, cooking time doesn't take too long, and portion sizes are good. But, there's a lot of competition on campus town and Mandarin Wok doesn't stand out much in terms of food.
