I'm not Kevin, but we enjoyed the burgers at Richter's in USO. They also have those cool 'build-your-own' coke machines!
We were under-impressed with Mythos. Tasty, worth the $$, but didn't live up to the hype.
We really liked The Three Broomsticks! Breakfast was universally yummy. Dinner was terrific except for the Cornish Pasties. they are nothing like the ones you can get in the UK and not yummy enough to be worth pretending.
We didn't get a chance to eat at CityWalk except the food court (blah). The poolside restaurant at Royal Pacific was fantastic (just beware of the DJ!

)
