We have eaten at all of the counter service in the WS. Here is a breakdown of our opinions:
Cantina de san angel- closed for now, who knows what it will be when it reopens. previously had mediocre mexican, slightly better than taco bell.
Norway- just sandwiches and desserts. some desserts are pretty good. doesn't really do it for us.
Lotus Blossum Cafe- bad value, not much food for the price. okay taste. plain white rice with orange chicken a little boring.
Sommerfest- good bratwurst, great desserts. seriously one of the best snack credits you can use on the plan. you get an actual baked dessert with a counter service credit. black forest cake, cheesecake or apple strudel. also have hot dogs, if your kids like that
Italy- will have a new pizza place in the future. hope it is good
America- not great. if you want American food, go for Sunshine Seasons in Futureworld
Japan- good food, decent portion sizes
Morocco- good portion sizes, good dessert selection. maybe not great for picky eaters as sides are cous cous and hummus. tasty, if you are into that
France- delicious desserts!!! absolute best snack credit place. have sandwiches, cheese plates, croissants and quiches for CS. they will heat up the ham and cheese croissants etc, and you still get the great dessert
UK- fish is fresh and good. shortbread cookie is only dessert option.
Hope that helps some!
