Love food? Love wine? Then I've got good news: there's no need for your cup (or wallet) to run dry while in Montreal. That's right, you can feel free to tote your favorite bottle with you to hundreds of Bring-Your-Own-Wine (BYOW) restaurants across the city.
It's true that the BYOB concept can be found in other North American cities, but nowhere have I seen it as common as in Montreal. We even have entire streets dedicated to the practice (Duluth and Prince Arthur Streets, both in the Plateau area, are lined with BYOW restaurants).
The whole process is very civilized. Simply purchase a bottle or two of your favorite wine or beer at the nearest SAQ (government-run liquor store), then bring it in to a BYOW restaurant. Now, you should know that BYOW restaurants often have a bit of a mark-up on their prices (20-30%) to make up for the fact that they don't cash in on alcohol sales, but you can still end up saving a pretty penny - particularly if you're the kind of person that enjoys a few glasses of good wine with a meal. There is no additional corking fee.
