I think it is great - very tasty, more food than I can eat (and I eat BIG breakfasts), and a really pleasant, calm dining area. Here's a link to the menu: http://allearsnet.com/menu/menu_tusb.htm
It used to be practically empty for breakfast. One time we were the only folks there (rode KS 1st thing, then had breakfast.) Now it is a little busier, but not too bad.
After the Crystal Palace, it is my favorite breakfast at WDW.
We're doing this as part of the whole AKL Concierge Sunrise Safari so it's a different breakfast buffet than the norm. However, in general I heard it's a decent breakfast spot. Their lunches, however, are supposed to be really delicious.
Thanks! We may have to give it a try as the breakfasts are limited in AK and we want to be there right at opening. I am debating on going back there for lunch or trying Flame Tree BBQ.
