In Montreal

...In the largest French-speaking city in the world after Paris, concierges or cashiers who greet you in French switch to fluent English when they hear your accent. A "typical" meal might be a $4 smoked-meat sandwich or a $100 six-course dinner, each essential to the Montreal experience.

In winter, the contrasts only grow as snowy streets give way to cozy restaurants and lobby fireplaces. Walkers shed their coats to stroll the underground city connected by 19 miles of walkways. And while residents of other northern cities hibernate, Montrealers come out to play.
