Scaddabush and I go way back as I frequented the Square One location when I lived in Mississauga. I am so happy to work nearby this surprisingly spacious location now. The ambience is just right and I've been here many times, and know I will return many more times.
The *only* downside is that the outdoor seating kind of sucks.. you're literally seated in single file along gerard right on the street, so keep that in mind if you want to dine outdoors.
I could say a lot about the food and rave about the fresh mozzarella like everyone else does, but I'll leave it at a few short recommendations:
The mozzarella with the pingue prosciutto
The meatball in any form
The charity bread because A) it's cheap, B) ain't nothing wrong with garlic, oil, and carbs, and C) charity
The shrimp pasta with capers -- though I think it is hit and miss depending on who is in the kitchen it can sometimes be really good
The grilled cheese with fig and prosciutto
The bruschetta (the classic one, haven't tried the others)
There are more good things on the many than there are bad, so pick with confidence!
