At Sunshine Seasons, the soups count as a "side" for your CS entree. We got the flatbread, a soup, and a dessert (strawberry shortcake - delicious!). You could EASILY share there - for 3 adults and my little boy, 3 CS meals was too much and we were stuffed all afternoon. You can walk around to any station and get whatever you want, and you pay for everything in the same line once you have all of your food. The stations each have separate lines to wait for food.
I think that Sunshine Seasons is the best CS in all of WDW. Absolutely fresh and delicious and terrific value. Everything is delicious.
