The Bleu Moon is a third-pound charbroiled patty under melted bleu cheese and red onion, and ordering one puts you in a dim basement kitchen off the Historic Fayetteville Square that has fed people since 1977. Get the homemade fries alongside, and save room for grasshopper crepes — mint ice cream buried under homemade hot fudge. Cramped, low-ceilinged, no view: you arrive because someone who loves you walked you down the stairs, and after that the room belongs to you.
