There are some good park options. We avoid both Potter restaurants.
Confisco Grill for TS in IOA and Thunder Falls for CS are both wonderful, with some good fresh choices and have never disappointed. Mythos is a hit and a miss for us, not somewhere we`d eat every trip.
Studios, we like Lombards. It`s usually spot on for food, Finnegans we have never really enjoyed for food, too greasy but good cocktails.
Haven`t eaten many times in Simpson`s food court, but it was ok.
Citywalk have some good choices for TS and CS. Bread Box we thought was excellent for CS, and we do enjoy Margaritaville, Cowfish, NBC and we love Vivo. We actively avoid Bubba Gumps and HRC, the latter only because we`re ancient and it`s too noisy!
And some of the hotels have very good options too.
