Hands down, Satu'li in Pandora. There were minimal waits on Saturday 6/3. Have read of people using the mobile order feature when it gets a bit busier and having their food within 5-10 minutes when it gets a bit busier.
Satu'li is a CS location on the dining plan - however the mobile order feature doesn't support using your credits - yet.
LOVED the variety of options and that Disney is trying to do something really healthy, but flavorful at a CS location.
It is a similar set-up to BOG - you get real dishes and silverware to eat on. However, you bring your own food to your table here vs. BOG bringing it to your table.
Pongu Pongu has some snack credit options as well. The name is escaping me at the moment, but they have some pineapple/cream cheese spring rolls that were to die for!
Before Satu'li existed - I would say Flame Tree.
