On thing you do not go at this location of Chez Dany is challenge the owner by having your friend rant about having the best pizza down the road - next thing you know the owner is cooking you up a special olive oil garlic spinach and mozzerella pizza and it's 3am.
I will note the pizza is so worth it.
Opening in the afternoon until late, this place offers up pizza, hot dogs, poutine (with baked fries instead of deep dried chips), and baclava to die for.
Oh yes, the owner doesn't seem to mind when you drunkenly walk in demanding poutine at 3:30am.
In terms of late night food you can get any better in terms of food quality and friendly service.
