It turns out there are Five Guys in the general vicinity, just not very close. I wandered over to the nearest (about 13 miles, one way), and had a small burger, w/o cheese, small fries, and small drink (which set me back about $9!) The fries weren't as bad as I expected, but I don't think I'll order them again. The burger was indeed small, though the gal at the register implied otherwise, but it was very good.
The place is expensive, though at least one restaurant reviewer thinks it's cheap. If I did it again, I'd get the regular burger and skip the fries, but I'm still not keen on spending $6.50 for a burger and a drink...and using close to a gallon of gas to get there and back.
I neglected to include that part of the value of the burger is that you get to order a few novel ingredients, such as grilled mushrooms, which I opted for.
