I have been to Montreal 5 times, and I have gotten "2 Dollar Chow Mein" 3 times. I know I am heavily biased, but of all of the ideas for street food I have seen: hot dogs, pretzels, BBQ, etc., this is by far the greatest. Chinese food on the street for all the drunken bar-hoppers? Freaking. Brilliant.
Last time I was in Montreal I was staying near McGill downtown and we went bar-hopping in le village gai. We walked nearly 2 km out of our way to get 2 Dollar Chow Mein. Damn was it worth it. Is this gourmet Chinese food? No! But the sauce is peanuty, the dish is hot, the serving is generous for a twonie, and the concept is incredibly novel and brilliant. Chinese food. On the street. Open til 3 am. New York, get your act together and get up on this!!
