My family and I are travelling from NJ to Montreal next week - we'll be there between 12/29 and 1/2. I've been calling around for dinner reservations and have found that many restaurants are closed. For the benefit of others travelling during the same time period, here are the results of my research: The following are closed: Brunoise, Anise, Le Caprices de Nicolas, Toque! and Joe Beef. Au Pied du Cochon is open on 12/29 and 12/30, closed 12/31-1/2. Bronte and Les Remparts are both open. Les Remparts has a multi-course NY's Eve menu with an 8PM seating, but it is fully booked. They are also offering a 5:30 PM seating where you can order off the regular a la carte menu. As of yesterday, they still had tables available.
Good luck! By the way, I've really enjoyed reading this website. Lots of great info.
