Le Plateau Mont-Royal - where the milongas are - amid residential and commercial streets often reminding you of Buenos Aires (architecture, colors, scale, personality). The green on the left indicates where the mountain is - a natural wooded expanse designed by the man who also laid-out Central Park in NYC. It's beautiful. Vieux Montréal is a 15 minute stroll to the south of Sherbrooke; major hotels and downtown shopping just a 10 minute walk to the south-west.
At the bottom of the Plateau, on St-Laurent, the De Niros and Clooneys and Schumakers often dine when they are here working. In the area you can get anything from yerba matte to falafel to corned beef to famous Montréal bagels; excellent French, Greek, Portuguese, European, Middle-East, Asian, Indian, African, South American cuisine reasonably priced. The world lives here harmoniously.
To give you an idea of scale, walking leisurely up St-Laurent from Sherbrooke to St-Viateur, where La Tangueria is, takes 40 minutes. L'Académie is half-way there; La Gitana around the corner. Mocha Jo's is a few minutes stroll from Tangueria.
Al Sur Tango is 5 minutes by car north of where the map ends, up St-Denis; Studio Tango is 3 blocks south of Sherbrooke where av. du Parc becomes Bleury. Tango Libre is at Papineau and Marie-Ann on the right.
Some tango people rent rooms to visitors. email Keith
