Flying Fish is closed for refurbishment. No indication that it will be open anytime prior to fall (maybe September/October.)
California Grill has bar seating with full menu available. but they won't let you up if it's full. Of course the last time I tried it I got resistance from the 2nd floor desk regarding "we think it's full" and they called up and finally let me up because I was just one person. When I got up there, there were only 3 persons seated at the bar (including me.) The lounge tables were, in fact, full, maybe that is what they meant. So maybe make sure they know that you'll accept a barstool.
Also, Sanaa lounge (they have a lounge menu but will let you order from the regular menu unless they are very busy), the Wave, Narcoosees, and Citricos. At times, Territory Lounge at Wilderness Lodge allows ordering from the Artist Point menu, but it must be during Artist Point operating hours. They have a couple of lounge menu items that are also served at Artist Point.
In the Epcot resort area, you can try the Crews Cup Lounge. I don't believe they allow ordering from Yachtsman's menu but they have a pretty substantial menu of their own. Or they used to.
Haven't been there but I hear you can order food at the bar at Shula's also.
