Although I feel like the chef must be tired of making burgers (it's the only thing on the menu that doesn't change), I admit that it was pretty good. It was flavourful and surprisingly light.
We did, however, find their salad and fries to be too salty-- and we are salt-loving people, so this was slightly baffling to us.
For those needing a break from the bustle of King West, Marben is a good respite.
