Yes - there have been a few threads on this lately.
I'd just like to say that you'll want to go to a CS with Air Conditioning in August! Believe me! That said, some of our favorite CSs are skipped when we go in August because we truly need a little AC break at the parks.
Our ol' stand bys (all AC):
MK - Columbia Harbour House
AK - Pizzafari
Epcot - Yakatori House (limited indoor seating - go at an off time)
HS - we don't eat CS here, usually get an ADR for Sci Fi Diner
