There are only a few TS restaurants at AK: Tusker House, Yak and Yeti, and the Rainforest Cafe that is right outside the AK gates. My DD didn't really like Yak and Yeti, but plenty of people seem to enjoy it. Also, we have an RC at home so we don't usually eat at one. So if you're already doing Tusker House, Yak and Yeti and RC are your other choices at the park. That being said, the CS places are air conditioned, except for Flame Tree, but they have nice covered, seating.
