I'm admittedly biased, because I worked at Citricos during my Disney College Program, so I have to recommend it. But I've had the chance to try just about everything on the menu (or the menu as it appeared a year ago), and it's all fantastic. The menu does change frequently depending on seasonal offerings, so keep that in mind.
It's true that Citricos doesn't have the most unique menu, or any major dishes that you couldn't find elsewhere on property. But the chefs are wonderful, so everything tastes excellent. The shortribs are the best I've ever had. I'm not a seafood fan, but even I enjoyed the fish and particularly the shrimp appetizer.
For appetizers, I recommend the shrimp, pork belly, or arancini.
For entrees, I'm partial to the shortribs, but I've heard excellent things about the pork porterhouse as well.
If you order anything other than the warm chocolate-banana torte for dessert, then you're cheating yourself. I'm still dreaming about it. Not only is the presentation gorgeous, but it might be the best dessert I've had on Disney property.
If you have any particular questions, I'm happy to answer. I can even recommend tables, if you're interested. The servers are all wonderful, as is the management, so if you go with Citricos it should be a great experience.
