For QS, if you know your way around a smoked spare, Flame Tree is a really decent value. Their ribs are not the best ribs on the planet or anything, but for QS, at WDW, they are pretty darned good, and not crazy overpriced.
Pro tip: Ask what the price is for the ribs only, the slaw and beans are garbage. Get a side of onion rings instead. I forgot to ask them about this last time, but if it was a decent amount less to get ribs only, I'd do it. Those onion rings are a hidden gem.
