I hope that nobody visits Montreal without going to the underground shopping district, which is bigger than can be imagined (one guidebook points out that if the underground city were laid out in a straight line it would be 20 miles long). Major downtown office buildings, half a dozen hotels, I think seven subway stations, department stores, the train station, multi-level shopping malls, and hundreds of small shops and services all inter-connect at the concourse level. And: there are so many food courts. The time to go is at about 11-11:30 AM when all is prepared to receive the thousands of office workers who will eat lunch there. Most courts are run by ethnic immigrants thus every ethnicity of food is offered, with rich possibilities for sampling and trying. At that hour everything will be fresh and gorgeous. Prices are rock-bottom. I can't think of a better place to graze. Don't miss this.
