Swolphin is incredibly overlooked. Their pool bar is by far the best on property, cosy couches and great food/drinks. The other restaurants speak for themselves and the Epcot resort area is obviously fantastic. It makes for a lovely evening
Bluezoo and Shula's are very, very good. Garden Grove is very, very bad. The seafood buffet at Garden Grove on the weekends is absolutely horrendously bad.
Disney Springs has a lot going on. I treated the food trucks like tapas and had few small plates that were really good. I enjoyed Homecomin' a lot. If you like Mexican, Frontera Grill is easily the best on property. I haven't been there, but I hear good things about the Polite Pig as well.
