I have been warned by some that this Mandarin wasn't great, however I had a good experience here. It close to the subway station, and parking is free up to 3 hours (Mandarin staff will stamp your parking pass).
I went on a Wednesday about 1pm, and the foyer was packed! I was surprised that a wednesday afternoon will be so busy, but the buffet price is cheaper at this time.
Drinks were refilled and empty plates were whisked away quickly. In most buffets you shouldn't expect the food to have the best quality but I did enjoy the food. There was a good amount of selection to choose from, Everyone at the table had something to eat. The best part for me was the dessert. Lots of dessert including ice cream, frozen yogurt and cotton candy.
I would come back again!
