This incredibly diverse street could be considered the city's chief east-west artery. At its western extreme lies the posh boutiques and restaurants of Westmount. It then runs through the heart of the downtown shopping district, past Simons, the Eaton Centre and Birks' Jewellers, to name just a few. Farther east, the street becomes the main drag of the Gay Village, with its charming bistros and seething nightlife. Vendôme Métro serves Westmount; the Green Line travels along Ste-Catherine as far east as Papineau.
