We're staying at All Star Music - do they have a restaurant that will serve dinner?

I'm not sure about ASM but last year this is what All Star Sports had at their food court, and though as tinkerbell60 says you might not get the atmosphere you want the food is good and price would make your DH happy:
All Star Sports

BTW - We've eaten the special turkey dinner at Cosmic Ray's at the MK on Thanksgiving day and thought it was actually pretty good. My DH liked that turkey better than the ones I make!

It was inexpensive and tasty with all the "regulars" like turkey, dressing (stuffing), mashed potatoes & gravy, green beans, etc.
You could also get it ala carte, so if you wanted a family style meal instead you could do that - for example, order a large mashed potatoes and gravy, extra biscuits/rolls, etc. Some people were doing that as a takeout.
Don't worry - at WDW you'll never go hungry
