My grandparents live in Lanzhou and I visit them every year or two. Therefore, it is safe to say that I know what a good bowl of lanzhou pulled noodles is and this place is the best one I've tasted so far in Montreal.
I only get their signature noodles with the second third noodles (er xi - I find them to have the best texture, nice and chewy but also soft). The broth is nice and flavourful, not quite as good as the real thing but close enough. The only thing that I find lacking is the spicy oil, back n Lanzhou, the bowl is covered with half a cm thick of spicy oil while here I had to nearly empty the pot on the table to achieve a something close.
The wait can be quite long an the eating environment isn't be best but overall great fix when Im missing a good bowl of lanzhou noodles.
