Flying Fish (on the Boardwalk; quick walk from EPCOT through the International Gateway) is probably my favorite place to dine at the bar. It has everything - great food & wine, beautiful setting and fantastic service - the bartenders are really great. In the same area, Crews Cup Lounge in the Yacht Club is nice and cozy with what I'd call pub food - burgers and such. Also in that area, just about all the spots in the Swan & Dolphin hotels have bars - BlueZoo, Il Mulino, Shula's - and they're used to convention attendees so typically plenty of solo diners. Jiko at the Animal Kingdom Lodge is another favorite … they have the cooking place which is like a small chef's counter where you can watch the chefs preparing some appetizers and desserts, ask them questions (if you want to) etc. I do make a reservation at Jiko though... it's quite popular and a bit of a trek to get out there - but worth it … the resort is gorgeous to explore. Just about every place in Disney Springs has a bar - my favorites are probably Boathouse, Wine Bar George and Homecomin'. In the parks, Nomad Lounge at Animal Kingdom, as mentioned above, and Tutto Gusto in the Italy pavilion and the Brown Derby Lounge in Hollywood Studios are all great. Note that the Brown Derby Lounge is outdoors with limited cover so it's weather permitting. Hope that you have a great trip!!
