It fucking rocks. The food is delicious, and the funny thing is... because it's in Arlington, it's mostly frequented by upper middle class and lower upper class people. People definitely make bank up there (which is why it's highly white suburbanite).
The photo op might be to evoke an "average Joe" image, but it's more like an "average suburbanite" image. Average Joe would be more like McDonald's.
For burgers, Ray's is some high quality stuff. If you're ever in the area, try Ray's the Steaks as well. Fucking delicious.
