Prices were kind of high, I think you're paying more for the dining ambiance than the actual food. The dishes can be pretty hit or miss, but in general I can describe the taste as being excessively bland. The only dish that I really enjoyed was the tofu appetizer, but you can find that in a lot of Shanghai restaurants. There are better and cheaper vegetarian/vegan places to eat in Markham, NY and Scarborough than Wu Tai. Would not recommend.
For any vegans out there, some dishes have milk, so don't buy them. If it looks like there's cheese or milk in it - there is.
