I first tried Five Guys at their Airdrie location, and it was excellent. The south location was just as good. Delicious food, huge portions, and a list of toppings that lets you make the burger *you* want (like Harvey's, but good).
It has "Diners, Drive-ins, and Dives" appeal, and although they might scare you when they yell out an order, you'll soon be drawn into the appeal.
Definitely worth stopping by.
