Les Enfants Terribles has one of the best summer terrace spots in Montreal. It's great in winter, too; I've had many a cozy meal here. The cuisine is French bistro comfort style, and I always enjoy the salmon tartare. It can get crowded and noisy, so best to reserve in advance if possible (though I've also managed to drop in and score a table). The wine list is decent, too. Afterward, walk down the street to Bilboquet for some of Montreal's best ice cream or sorbet.
