We were just there yesterday and we ate at Plaza Inn on Main St.
They have very good fried chicken (1 1/2 chicken). We get double mashed, no grean beans (I love green beans, these are bad). My DD11 and I share it.
Another favorite is Pizza Port in TL.
We like the Chicken Fusilli (DD loves this

) and the Chinese Chicken Salad. If it's just the 2 of us we get one or the other to share. If we get the pasta many times I will get the small side salad and get the Asian dressing. It's so good!
You asked for DLR so if you want more than just
Disneyland here's a few more
DCA
No real favorite inside the park. We keep meaning to try the Cove Bar but haven't yet. The chicken wings sound good.
I'm looking forward to the new Pasta place opening soon. Hopefully it'll be more like Pizza Port than Pizza Omm Mow Mow (which it is replacing)
When we are at DCA we will many times go to White Water Snacks in the GC. Good nachos and chili dog.
DTD
We love Ralph Brennans Jazz Express. Gumbo Ya Ya, Beignets, kid's meals are all good.
Sit down-House of Blues. We use a certificate from restaurants.com for about a 50% savings.
We don't do a lot of table service meals while at DLR so I don't have many rec. for those. Used to love the Pizzetta Salad at Wine Country in DCA but the redid their menu and took it off so we haven't tried it again. I hear it is still good and in good weather sitting outside on the terrace is lovely.
Cafe Orleans in NOS is pretty good. The Pommes Frites are very good!
