There are many great items to try at Landscape of Flavors for both the lunch and dinner periods (the menus are very similar). Because this food-court style eatery is the Art of Animation Resort's only restaurant, multiple visits should be pretty easy if you're staying at the resort.
The large open-concept dining area has ample seating for everyone and is themed with various paintings and artwork from the same animations, that also theme the resort. There is a "Cars" area for example, that has prints and scenes of Radiator Springs hanging on the walls.
Most of the seating is indoors but there are a few tables outside as well, for those that are enjoying the pool area, and don't want to be inside the air conditioned restaurant.
The restaurant can get busy at peak times, and this is one of those "hub and spoke" set-ups ... everyone has to go to a different counter to get what they want, and then get back together at the registers to pay … this can cause a few delays. If you go once, you'll have a strategy that works well for your group, but that first time can be a bit confusing.
The food here is squarely American and very similar to other food-court and quick-service locations in the Disney Resort dining system.
There's a Pizza and Pasta Station, some hot and cold sandwiches, a couple of salads and soups (seasonally), etc.
For the dinner period, there are also a couple of unique entrées available, Naan Bread and a Tandoori oven have been staples at the Landscape of Flavors for quite some time now, and there's usually a few dishes made with those... such as the Tandoori Boneless Chicken Thigh served with Naan Bread and Jasmine Rice.
There are a some baked goods for dessert, but most are stored in a "serve yourself" presentation display. There aren't really any "prepared" dessert here, with the exception of hand-dipped Gelato station.
