My usual place is the Smokehouse. I think they renamed it to something like "Smokey Creek Grill" or somesuch. I LOVE their beef brisket platter. It is divine! I almost always eat there. Heck, I'll even stop by just for the heck of it when I get the BBQ craving.

It's reasonably priced and delicious.
I'm also a recent convert to the school of Sharks Underwater Grill. I don't eat seafood, which made the menu rather limited.. but the service was awesome, the food was great, and the atmosphere is top notch! Only complaint was that there were too many screamin' babies in there. But it's to be expected at any theme park restaurant. The price is a bit high, too. But the food was great!
SeaFire Inn has good burgers, but I don't eat there often as I'm just not as impressed by their price or selection. Very good burgers, though.
I've never tried the pizza at Voyager's, but I have had their pasta. It was pretty tasty, but nothing special. But good nevertheless, they put a LOT of it on the plate... at least by my appetite.
And if you're looking for a whole dinner experience... I HIGHLY recommend the Makahiki Luau! Fantastic food, fantastic show... just awesome!
