We had lunch at the Five Guys in Rio Grande, NJ. As we were looking for a likely lunch pick, I at first didn't understand why my companions seemed so eager to stop at what sounded like an auto supply store. Once inside, Five Guys' true identity as a burger joint was revealed.
I had a regular burger, not realizing that meant I was getting two beef patties instead of one. My chosen toppings were just lettuce and tomato, and of course I got fries. It ended up costing a bit more than I had expected for "fast food," but at this point I was in "investigate new dining option mode," so it didn't matter. The potatoes that made our fries came from Driggs, Idaho, county seat for Teton County (thank Yog-Sothoth for the internet!).
It seemed odd that everything was served in a paper bag, even though we were eating in, but I just ripped open the bag and tucked in. Fries in a styrofoam cup: also odd. But after the first fry, I didn't care. The burger patties were clearly hand-shaped (rustically irregular) but very juicy. When I discovered Five Guys cooks all of its burgers well-done, I was shocked because I don't think I've ever met a juicy well-done burger before. The lettuce and tomatoes were pretty standard-issue, but very crisp and fresh. And the fries, the fries...it was a good burger but the fries were phenomenal. Crisp, fresh, unskinned, salty but not too salty, piping hot...they were the best french fries I've had in a long time.
After the fact, I came home and searched for posts about Five Guys on the Chowhound boards. I didn't read them all, but there were a ton of them, divided between Five Guys lovers and haters. I should have guessed as much, I suppose; for every good review of a given restaurant, there's a bad one (or vice versa). At least, it seems that way when one trolls for restaurant reviews on the internet.
