Get the tapenade burger while it lasts. Add some caramelized onions to perfectly balance the thick slice of creamy goat cheese. The black olive tapenade is a little too salty and overpowers the rest of the burger so I would put half of it aside on the plate. In terms of texture and taste, this is by far the most satisfying burger under $12 in Montreal. If you're taking fries, I suggest taking spicy fries with no salt (the cajun spice is already quite salty).
I order my burgers medium nowadays at BDV. Medium-rare tends to be too rare and lacks texture. It's less char than I remember way back then but still excellent value.
Topping pairing matters. Don't blame poor combination on the house.
