I attended a soft opening of this spacious second floor King West newcomer. This is not a newcomer to burgers... I've been a big fan of the Montreal location since it opened a couple years ago. To customize your AAA, organic or kobe burger there are a variety of mouthwatering toppings that range from smoked bacon to shaved truffles (prices range too). The location includes fully stocked bar with a variety of wines though sadly they've not brought the Quebec microbrews with them.
The sesame buns are fresh and just large enough to allow for several add-on toppings. I chose buffalo mozzarella, bacon, caramelized onion, horseradish mayo and of course a fried egg (I shied away from the Michigan sauce - aka chili - on this visit). Of course it was tasty, the burger alone tastes great with the right balance of saltiness and seasoning. Famous Moishe's coleslaw is a nice side along with a basket of sweet potato fries.
Oh and there are various other non-burger items on the menu - don't let the name fool you. I have never ordered anything else here but the poutine looked great and was certified as excellent by a young girl sitting at the table behind me. Desserts also look very tempting but my burger and sides were filling enough. Pulled pork sandwiches, chicken, tuna and even mac and cheese are vegan options (to me a vegan is anyone who doesn't eat beef).
With several Montreal-based team members relocated to Toronto I think Mbrgr should see a successful opening this month.
