This is the only Five Guys location I've ever visited with any regularity. I come here only when I'm hankering for a burger (and they ARE good burgers), but this is by no means a default food stop for me. The amount of food you get for the price you pay is easily outclassed by Chipotle, which happens to be right next door.
The wait time is actually considerable; I wouldn't call Five Guys "fast food". That's not really a bad thing, since true fast food burgers are disgusting. Nevertheless, be aware that you could be waiting 15 minutes for your food, though you might not even notice as you ravenously eat their abundant supply of complimentary peanuts.
The decor is awful. I always feel like I am standing in an oversized public bathroom. Consequently, I've never had even the slightest desire to dine-in.
