After visiting MTL a few times this has become a must stop on the list of places to eat. Mai Xiang was recommended to me by locals and it does not disappoint!
It's a small spot that tends to be packed for dinnertime. The dumplings are made in house and each order comes with a decent serving (I'd estimate 15-20 dumplings). Definitely enough for me to eat and have a leftover to snack on later. Authentic Chinese dumplings! My favorite is the pork and mushroom with a side of the cucumber jellyfish.
It seems like somewhat of a family operation so staff is minimal but they get you your food ASAP and you go up to the back counter to pay when you're done.
CASH ONLY! I always forget but they have an ATM at the front door if you're like me.
