The Beaver Club restaurant is located on the lobby level in the Queen Elizabeth Hotel (see other journal entry) in downtown Montreal.
The Beaver Club is very nice and upscale. They have fixed-price options (Table Hote' and very popular in Quebec) where you can select courses from the menu, for around $60CDN per person.
I had Romaine salad, leek soup, filet mignon, and dessert...all were great.
Two in our party had jeans on, and were initially refused entry, but upon learning that we were staying at The Queen Elizabeth, they bent that rule. I wouldn't count on being served in casual attire.
Plush place, great service, and great food. As long as your dressed, why not?
