When dining on upper St-Laurent, skip the last course and make a beeline to Kilo. The mousses, cakes, and pies sold here are arrayed as enticingly as jewels in a display case. Light lunches are served, but it's the desserts, sweet and creamy or tartly piquant, that draw the crowds and pose a direct challenge to the most determined dieters. Strong coffee laced with cognac, amaretto, or Grand Marnier is often chosen to complement the sweets. They also have a branch at 1495 rue Ste-Catherine est (tel. 514/596-3933).
