Strangely enough, my favorite meal was a quick, casual one at one of the bars. It's the bar at the Polynesian, located by Kona Cafe - I think it's called Tambu Lounge.
We had the best chicken/lettuce wraps ever! Amazingly yummy, and pretty healthy, too, as WDW food goes. A plate is a meal for one, or a shared appetizer for two people, and costs around $8. So good!
