Love this all you can eat buffet. I have been here a few times and each time I was impressed by the wonderful service and super friendly staff (even better than the other Markham location on Woodbine Ave). This is in a newer area and therefore it is not crowded and very clean.
Mandarin is typically more expensive than other AYCE style buffets. But you get what you pay for. Quality is consistent with food matching the theme (eg. moon cake during mid-autumn festival). However it doesn't have as much authentic chinese food (eg. dim sum, soya beancurd pudding) and is more westernized with deep fried chicken wings, chow mein, corn and mash potatoes. Also not as big selection as other large AYCE buffets (eg. China Buffet King in Richmond Hill many years ago before they closed down).
Overall, this is my favourite Mandarin location so far. Beautiful decor. Service is always excellent. Food is fresh and well presented. Definitely a wonderful buffet to bring your friends/coworkers.
