Sunshine Seasons was my favorite CS place in the entire WDW. There are a lot of choices from salads to rotisserie chicken to Asian stir fry to freshly prepared sandwiches. My kids had mac 'n' cheese and chicken drumsticks with mashed potatoes. And the desserts here to amazing. Plus, there's a lot of fresh fruit to choose from if that interests you.
We liked the dessert from our lunch so much that on our next Epcot day, we used 5 snack credits here: DH and I both had fruit tulips, and the kids had chocolate chip cookies and worm in dirt.
The food is certainly a higher quality than the standard CS places in WDW, and if you're over in Future World, the only other option is Electric Umbrella which is just disgusting. So my advice is to go to Seasons and enjoy. But just as everything in Disney, if you arrive at the peak time, you'll find yourself dealing with crowds.
