I wanted to check this out since a fellow friendly yelper had mentioned this place for its authenticity.
Overall it was an decent experience food-wise with a highlight on the peanut butter shrimp dumplings, corn soup with egg swirl (good job on the swirling) and Gai Lan was done great with loads of garlic.
The cons would have to be the stale smell in the air. I know I wasn't coming here only for the atmosphere, but it distinctly smelled like a a memory from back in the day, a combo of mothball, incense, old carpets and not too circulated air. Having said that though, you forget that it does smell like that after 20 minutes.
I'd definitely do take out here for the food, as it is better than some of the others in Montreal.
