Absolutely do not go to these places, Capn Kids (gross disgusting nasty food) and IHOP (way overpriced, we spent more eating at IHOP than we would have eating at DL).
Eat here, Millie's (good food, good prices, large portions), Mimi's (great food, good prices, large portions), Denny's (standard Denny's food and no price hikes). Those are on Harbor. In DTD you've got Rain Forest Cafe (good food, good prices, huge portions), Ralph Brennan's Jazz Kitchen (great food, good prices, huge portions), ESPN Zone (never eaten here), House of Blues, Catal, Uva Bar, La Brea Bakery (good breakfast stuff and sandwiches), and a couple of little Italian places and I'm totally blanking on the names...Napolini I think, or maybe it's just Naples. Sorry, I don't remember. Anyway, the DTD restaurants are 5-10 min tops (walking, if you take the monorail you cut the walk time down depending on where you go but you will have to wait for the MR) and the Harbor places I suggested are about 5. Wait times will vary based on DL crowd levels and the times you go to eat. If you will have a car or are up to walk another 5-10 min. go to the Garden Walk, there is a CA Pizza Kitchen, PF Changs, Cheesecake Factory, Bubba Gump and other places that I can't remember there.

If you'll have a car drive to the GW or drive a bit farther to the Target area and right there you've got a Red Robin, Joe's Crab Shack, a pizza place and an Outback.
