You can order pretty much anything from the restaurants at the GF, so take a look at the menus for Citricos and Narcoosees, etc. I have had numerous dishes from both of those restaurants that were very yummy. Order whatever interests you.
Here's a link to the GF menus here on the DIS: http://www.wdwinfo.com/wdwinfo/dining/searchoutput-loc.cfm
