As with nearly anything you post here, you're bound to get folks coming down on both sides of the issue. And, as with anything you post here, a lot of it will come down to personal tastes and your schedule, along with several other variables. One big variable is whether you are staying on or off site. I'm going to guess off, because it sort of sounds as if you were considering holding off until you're out of the World and on your way back to wherever you might be staying.
Having said all that... my opinion would be to stay in the parks, or perhaps venture to one of the resorts, or Downtown Disney. Yes, there is some bad food to be had in the World. But if you look into what you're really after, peruse the menus via the websites, get some feedback from your friendly and oh-so-willing-to-share-their-opinions fellows on this board, I think you'll find there's a lot of good food, as well.
After years of taking a beating for their poor food, Disney started really working to change that reputation several years back. As a result, there are a fair number of fantastic restaurants. You'll hear a lot of people rave about Boma over at the Animal Kingdom lodge (I'm making my priority seating arrangements for a dinner there as we speak, having not yet tried it), Spoodles, California Grille, etc. There are also places much cheaper with good (dare I say, on occasion, pretty darn great?) meals to be had.
Plus, from another perspective, I've always liked the idea of making the magic last as long as possible, so by eating within the parks or at one of the resorts, you're doing that. It may cost more than stopping somewhere outside the kingdom, but then again, maybe not. There are plenty of overpriced, not-so-great restaurants to be found in the Greater Orlando area. That's not a market Disney has cornered by any means!
So personally, I say find someplace on property that's fun, comes recommended, has the kind of food you want and is within your price range. I suspect you won't regret it at all.
