You will more then likely hear loud banging sounds, especially when the M80s go off, from inside the restaurant. We have been inside BOG, Tony's Town Square, and CRT while Wishes was going off and that is what we heard from those restaurants. I really don't think there is any restaurant that will completely hide the sound of fireworks, you may be better off going on a ride either in POTC, JC, or maybe even Country Bears Jamboree, even Buzz Light Year Space Ranger spin...go to a land that is a bit further away from the castle.
