We've been to Food & Wine several times - actually, generally plan our WDW trips around it
My one big recommendation is to avoid going on the weekends - it is so, so, SO much more crowded. There are a number of really good things we have had in the past - though part of the fun is getting to try things you likely wouldn't order a full meal of and the vast majority of the offerings are big enough for splitting if all you want is to try things.
Some really good things that come to mind are:
- Kalua slider from Hawaii
- Mongolian beef in Steamed Bun from China
- Scottish Banoffee Tart from Scotland
- Ravioli from Italy (and it is huge so plenty to share)
- Berbere style beef from Africa (it is a little spicy so perhaps not for you)
- Grilled lamb chop from Australia
- Pork belly from Brazil
If interested, starting on page 15 in my TR from October 2013 has our take on a number of items:

BTW - you might actually be really good at tasting wine if you palate picks up flavors that well. And even though you said not to try to talk you into trying an alcholic beverage, you might want to give the grapefruit beer a shot while you are there - especially if a hot day it is very refreshing.
