I have no idea what the fuss is all about. I tried 5 Guys for the first time today, and as a burger connoisseur I was excited.
The place was dumpy with the cheapest of furniture and not too clean.
The burger (two patties) was way way overcooked and so incredibly dry. The bun hardly covered the burger. I will say the toppings were really nice. I also wasn't impressed by the patty size, smaller than any other gourmet burger joint, making it hard to cook the meat anything but overdone. The cheese is processed which says too much about this places lack of commitment to providing a true quality product all around.
Service was fast and friendly, but I won't be returning and can recommend a half dozen better Gourmet Burger joints in the GTA.
