At Uni, my favorite place to eat is Margaritaville. Not only is it decent food, but I'm a big parrothead, so it is like heaven for me.
The boys always enjoy at meal at NBA City. Tons and tons of basketball crap - the menus are even made of basketball material. They have foot impressions from bunches of famous b-ball stars, like Michael Jordan, and you can put your foot in and compare - that's kind of fun.
And if you have younger kids (or just always wanted to do this), you can eat Green Eggs and Ham at...Green Eggs and Ham.
You can find regular food almost everywhere at Disney.

It just depends on what you like.
My favorites (but everyone has their own):
Magic Kingdom:
Breakfast - Crystal Palace
Lunch - The Plaza
Dinner - Liberty Tree Tavern
Epcot:
Breakfast - Ugh. Really bad fast food at Electric Umbrella or Princess Breakfast at Akershus. The Princess breakfast is adorable - all those little girls in their Princess dresses - but more commotion than I like for iffy food. I don't eat breakfast at Epcot.
Lunch - Garden Grill or same as dinner
Dinner - Mexico, Morocco or England
AK:
The only restaurant there (right now) is Rainforest Cafe and I don't care for it. I'm eager to see how Yak and Yeti's (when it opens) will be.
MGM:
50's Prime Time Cafe - really fun
Hollywood & Vine - loved it before it was characters, don't go now. I can only take so many character meals.
There are lots of good meals to be had in the restaurants. My favorite is a stop at the Wilderness Lodge - you can eat (very regular people food) at Whispering Canyon Cafe (a fun restaurant) and then head out back to watch the geyser go off - that's a treat.
The dinner shows are decent, too. I love the Hoop-Dee-Doo review. A great show! And absolutely not frou-frou, by any stretch. The Poly Luau is a nice show, too, with decent food.
