I never had Five Guys before!
I also didn't know they offered free peanuts. So once that knowledge was acquired, there was no more turning back.
We went there for a quick lunch and ordered a pair of burgers and fries. Then we sat down are devoured a whole bunch of peanuts. They were not the best, but hey ----- freeeee fooooood. The burgers were good, but nothing special. In the family of fast food burgers, they place slightly above McDonald's for me. I would probably eat Five Guys again, but most likely because of the peanuts than the burgers.
I can't image how delirious McGill's squirrels would be to infiltrate this place!!
