The best there is. If you love burgers, you'll love Five Guys. This location is as fine as any I've visited in the states. Clean, prompt and with friendly staff who genuinely seem to care about running a good ship.
If you've never been, I'd recommend ordering a "little" cheeseburger; the regular cheeseburgers are actually doubles. Personally, I think the balance of bun, cheese and meat is perfect in the little cheeseburger, but sometimes you just need a little extra meat.
