For some reason the onion rings genie is always on the move, dwelling for a while at one particular burger joint or full-menu restaurant that is home to wonderfully fresh fried onion rings — still crisp and juicy at the center with a paper-thin coating of flakes. Then suddenly the onion ring genie flies off from there, leaving behind a dreary wake of sad, vulcanized, vaguely onion-like fry-somethings useful only as patch material for small roof repairs. For however long it lasts, the onion ring genie is currently residing at Stackhouse, a cozy burger joint with a good beer selection across Gaston from Big Baylor. It's a hangout for the medical people, so, if you have a sensitive stomach don't examine their clothing too closely before you eat. Or, if it's too late, ask the people behind the bar to sprinkle some blue cheese crumbles on those rings. Sometimes that helps.
