From my experience Quebec has the best casino in Canada, so I'm writing this based on my experience from two years ago when i went to Montreal with my friends, i thought we might as well go visit casino. We gambled till we felt hungry, most of the restaurants are quite expensive and the buffet has the shortest line. I'm not a big fan of buffet because my expectation in food is higher than average, I would choose quality over quantity.
One of the best buffet I've been in Canada. We got in and then walked around, the selection is amazingly good with lobsters, smoked salmon and other seafood.. So far nothing had disappointed us.
One thing that blew my mind out, it was the Bûche de Noël / Yule log that they served.
The best dessert in the house, I believed they only serve this seasonal during Christmas! I cannot recall what the top part was but the middle was icecream and the bottom was crispy, the combination creates an interesting texture as well as a taste of heaven for dessert lover! The decoration of the cream with a blueberry gives an extra taste of Christmas.
