Despite wiki's (http://en.wikipedia.org/wiki/Montreal_Pool_Room) claim there are no more pool tables in the Montreal Pool Room there are some in back.
The Montreal Pool Room is ground zero in Montreal's steamé hot dog culture. You can get it all dressed (covered in onions, chopped cabbage, and mustard) or au Michigan (with meat sauce). The steamé is some cheap eats although a combo with drink and fries puts a couple dogs in the Harvey's double burger combo range. The fries beat the ass off of Harvey's, that's for sure. They're like Harvey's fries before Harvey's Inc. became real douche bags about their fries and tried to cut corners.
The joint is pretty minimal. Lots of floor space, few tables. I suspect the floor space might be there to simply handle lines for patrons who stumble in after closing hours (assuming Quebec has closing hours).
Service seems a little guarded. Probably owing to them sharing the street with some strip bars and other crèche de excitation nudity rub rubs.
