Olivia's is one of my favorite "hidden gem" restaurants. The food has always been good and filling when I eat there, and the service has always been outstanding. I'm in the midst of eating my way through all of WDW, and Olivia's is one of the few I regularly repeat dining at!
Gurgling Suitcase also has good bar snacks (and adult beverages) and Good's is, well, good if you need a quick bite.
Disney Springs is also just a short boat ride away, so there's also easy access to all the restaurants located over there.
