Messini is one of my favourite restaurants in the Danforth, largely because they offer a killer vegetarian pita (which, speaking as a firsthand member of a largely meat-eating greek family), is a goddamn revelation.
Eat the Greek fries. No really...they pile feta on top and bake it until it cries. Among my circle of friends I always play designated driver on Friday nights, but if I was drunk and hungry...I wouldn't settle for anything other than Greek Fries from Messini.
PS - The owner is a killer dude. Tall, Greek, gold chains and a chest of hair that would make Chuck Norris bow down in submission. It just adds to the ambience.
