Went there on a Sunday right before 11 am and were seated right away. By 11:15am there was a long line.
Ambiance: Large yet tight (all the tables are very close together). Bathrooms are tiny. There was some guy puking in the sink in the guy's bathroom.
Service: We weren't even served water or asked if we wanted to purchase drinks. We saw some waiters speaking English to other tables but they would barely acknowledge us. At one point it felt like we were being dismissed because we were the only brown people in there. We go to New York Chinatown all the time and never felt the way we did at this place.
Food: Honestly, nothing that stood out to us. Some of the dumplings were okay. Many of the carts didn't even come our way. Half the time they don't tell you what's in it. For example, they assured us one dish was just pork, not shrimp, but we found shrimp in it. This is dangerous for someone with allergies.
This was the second Chinese restaurant we visited in Montreal and I have come to the realization that Chinese food in Montreal is mediocre compared to Chinese food in New York.
