Went here last night and really enjoyed it! I agree with the other reviewers that the place itself doesn't look fancy but it delivers on the food.
The burgers are grilled right in front of you and they have a wide array of toppings. Unlike other burger/sandwich places, they don't charge extra for guac (which to me was a definite plus!). I thought the spicy fries and poutine (my husband and I each ordered one) were just ok - as someone mentioned earlier, they make them well before the burger is done so by the time you are eating, they are no longer really hot/fresh. The meat for the burger was juicy and fresh.
The staff are really friendly and nice to talk to and there is a comfortable vibe, like those neighbourhoods in the movies where everyone knows each other.
Just FYI - they only take cash. There is however a TD bank a couple of doors down.
