There are many good cs options in Epcot; however a few really stand out from among the others. IMHO the best are below.
Sunshine Seasons (The Land Pavillion). This place has an incredible selection that will please everyone in the family. This place offers a nice variety of salads, burgers, wraps, rotisserie chicken, and many other items on the menu which are very good.
Tangierine Cafe (Morocco Showcase) This is my favorite cs in all of WDW. I love this place. Very good wraps, but my favorite is the Shawarma Platters. If you are on the
DDP, this is the best value of any cs in the entire kingdom.
Boulangerie Patisserie (France Showcase) This place offers the best bakery items in all of WDW (IMHO). In addition to the pastries and desserts, they also offer some nice wraps and a few other lunch items. Many of the desserts are eligible on the DDP snack credit and are an excellent value.
