I have come around on Mandarin....
i went a few times to the big one in Brampton just off the 410 during lunch and always felt like garbage after. Might just be from going at lunch and the food isnt as fresh.
But I have been to this location twice on super busy nights (one being Christmas Eve) and the food was good! I went back for spicy chicken several times. We also came during dumpling festival and loaded up several times.
I wish there was a way you can have them not talk to you so much lol
just let me overeat in peace! I dont need the hostess chatting with me and the manager coming by and putting his card at the table.
Foodwise though, i think the best recommendation is to go when it is semi-busy so you know it is fresh.
