South St. Burger does make burgers better. you do have to pay more to get more though.
some of the distinguishing features are:
hormone free beef patty - thicker and juicier than McD/Wendys
bun choice of white or whole wheat
toppings from gourmet ketchup, mustard, mayonaise, cheeses
accompanying fries are NY Fries
Cost is ~$10 for a regular burger meal (burger/fries/soft drink) but the taste is more satisfying than McD/Wendys
something of this higher caliber class is like Hero Burger
The space is well lit, building is a corner unit with variety of seating to suit your fancy, a choice of rounded booths, to conventional tables and bar seating along the windows edge.
I've visited a few times at this Steeles location and I would say it's been consistently good most of the time. I recall one time the bun was burnt and I requested that I get another bun re-toasted. This was done no questioned asked.
Franchise experience should be consistent, the environment, food all has been predetermined, it's usually the staff that can make it or break it for a location.
