This location is bigger than their original Gerrard store. With lots of seating (though the booths are tight!), this is a good space for groups and families.
While I enjoy the burgers at GBK (the voodoo is one of my favourites) their poutine is the better draw. I find the fries crisp on the outside and mashed-potato on the inside - perfect. Fries seem more consistent than the onion rings, so your mileage may vary, but both are good.
Their patties are (sadly) not gluten-free, but are really tasty. Prices are decent, though not cheap. GBK is my preferred burger joint in town these days.
