The chicken souvlaki on a bun at Square Boy is the best deal on the Danforth. I prefer it on the bun over the pita. The buns have always been soft and fresh. The helping of chicken souvlaki is a good size and has never been dry. Also they put tzatziki and a lemon sauce on it, so it is definitely not a dry sandwich.
You don't have to wait to taste the Danforth for 5 dollars during the crowds of taste the Danforth. Just get yourself a chicken souvlaki on a bun for 5 bucks anyday at square boy.
