I would say that Jiko is probably one to avoid for the unadventurous. Take a look at the
menu. It's a shame because AKL is a lovely resort to visit, particularly in the evening. You'd probably find Boma a better option.
I really do like bluezoo (and whilst it's mainly a seafood place, elder dd had the most succulent double pork chop there), but for those who're looking for their first resort restaurant experiences, it's as much about seeing the resorts as eating at the restaurants, so the Dolphin (which, of course, isn't a Disney resort as such) probably isn't the best place to start.
The BoardWalk is a fun place to visit. We've outgrown Spoodles a bit, but I'd still recommend it to anyone who hasn't tried it before. Flying Fish cafe is a step up and very popular for a good reason. ESPN is a great place to grab a burger or chilli cheese fries, especially if you're a sports fan (or enjoy the sports bar experience). Another, little known, spot we enjoy is the Crew's Cup Lounge at the Yacht Club. It's the bar which adjoins the Yachtman's Steakhouse and we often go there for a burger and a beer. You can also order from the Yacthman's menu.
With the exception of Victoria and Albert's, I still think California Grill is the best food to be had at any Disney hotel (excluding the non-Disney Swan and Dolphin as they have some places which are probably as good). In a similar vein are Artist's Point at Wilderness Lodge (another lovely resort to check out), Flying Fish Cafe which I've already mentioned, and Citricos and Narcoossee's at the Grand Floridian. We ate at Narcoossee's for the first time last October and our entire party (7 of us) thoroughly enjoyed it. We got to see Wishes from the verandah which was a bonus.
