My vote is for California Grill and Wishes. My family did this on our last trip, and it was great. The food was some of the best I've had on Disney property, and it was great to get a different view of the fireworks (almost a top-down view). However, I'd highly suggest seeing Wishes from the main street area first to get the full impact of the show and doing the grill on a later night, perhaps on the last night of the trip, like we did.
