So so so so so nice. I ordered a hot dog against my better judgment and it was nevertheless awesome. They sort of slice it lengthwise and serve it more-or-less like they would a burger. One acquaintance who has more experience than I do with Five Guys says these guys are a little skimpier than usual about filling your bag up to the top with fries. But hey, I didn't know they actually did that at all (I haven't gone in years), so I wasn't about to complain.
Had a bite of a homie's poutine too and it was worth it.
Also, don't feel too guilty! Fries are nutritious! So much Vitamin C!!!
