You must be kidding me. I don't get what people are talking about when they talk about the underground city (much less as an actual tourist attraction). Tourists all know about it but ask any Montrealer and they scoff at the very idea. The \"underground city\" is nothing more than a series of interconnected shopping malls on St. Catherine in the downtown of Montreal. Lots of boring, overpriced stores (just remember: if you miss one Aldo shoe store, just keeping walking and you'll be sure to find another) and crappy food courts.  Sure, wandering through that dizzying maze of consumer nothingness is preferable to walking outside when it's 30 below in February but that's not saying much now, is it?
