Hmmmm...We've always enjoyed the chicken salad and the roast beef sandwich at Electric Umbrella.
For breakfast, I enjoy grabbing croissants and fruit from Fountainview Cafe and sitting at the tables outside.
Dh and older ds have enjoyed a variety of items from Sunshine Seasons. I can't say that it does anything for me.
For just a sweet treat, I love to grab something from the Kringla Bakeri or a cannoli from Pasticceria Italiana.
Rather than taking time to eat at Marrakesh last trip, we grabbed a bite from Tangierine Cafe and ate while watching Illuminations. While the view from the covered eating area was pretty good (no crowds that night), the food did not in any way compare to that found at Marrakesh. I found it ok...nothing more than that.
Lunch last trip at Cantina de San Angel. Not as good as your local Taco Bell. Sorry.
Personally, I like to walk over the Beaches and Cream and grab a bite there rather than have CS at Epcot.
