Sorry, 5 Guys is shit. If you're in the DC area (the home base of 5 Guys) it's Ray's Hell Burger, where you can get marrow as a topping, among other things (just gimme bleu cheese).
Well, my burger was well cooked, the meat was good quality and the extras were fresh, nothing close to shit. Sounds like the chain may be having a problem with consistency.
Ray's does sound good though!
