Mmmm burgers, a good burger is god for me and craft burger does them pretty well. Personal favourites are the Craft Spicy and I believe it's the Craft Crazy? the one w Coleslaw on the burger but i sub the pepper jack for smoked cheddar and no peppers, so really it's just a craft spicy w coleslaw...
They definitely focus on quality over quanitity, the burgers are a bit smaller than some of the ones I've had at the nicer burger places in that price range, and their portion of fries are not piled high but I prefer this as I can finish it enjoyably in one sitting.
If you're looking for something a bit more substantial though you could try a double patty or their milkshakes? I've been meaning to try a milkshake but always end up too full to order one.
