'Ohana's (if you can get it, this is always my most difficult ADR to get) @ Poly (although I've heard Kona is good, haven't eaten there myself)
Boatwright's @ POR (decent food and atmosphere)
Olivia's @OKW (decent food; noisy atmosphere)
I would suggest Wolf Gang Puck Express at DTD but it's neither TS or at a resort but it is one of my new most favorite places to eat (TS or CS).
I'm not a fan of Boma's, any restaurant at GF, or WCC @ WL.
If you're looking to use two credits Cali Grill and Jiko were two of the best meals I've ever had.
Good luck!
