Came here last Sunday for an early dinner with family. This is our second visit to Wu Tai. We had a groupon, which made the otherwise pricier meal (for a Chinese vegetarian place), quite reasonable. We ordered 4 dishes and one dessert and although we had asked that the dessert be served last, it ended up being served first. When we had notified the first waitress, she acknowledged the issue, but walked away. The second waiter was able to bring the dessert back to the kitchen to be served later.
The presentation of the dishes is nice and the taste and quality is great. However, be warned that service is slow. The dishes were brought out one by one with a considerable wait time in between dishes. Both visits we ordered a noodle dish and both times it was brought to the table last when we've already pretty much finished the rest of the dishes.
I would come back as I do think it's good quality and the food is yummy. I would suggest going earlier for dinner as it does tend to get quite busy closer to the peak dinner time.
