Also 'Ohana at the Poly has a lovely view and music piped in, but you are not guaranteed a seat by the window. I recommend eating dinner and then heading down to the beach or boat dock, where the music is piped in via little mushroom-shaped speakers. If you can hear the Polynesian music, you will be able to hear Wishes. Also, the EWP passes by at 9 PM every night, which is a nice bonus if you happed to be there.
There is also an obervation deck on the 4th floor of the CR, but it is outside and not connected to a restaurant. I think the music is piped in there.
