The Atmosphere in the Prime Time is great! It's one if not the best on Disney property. I'm assuming you know the drill there, if not just ask and someone will explain it to you. The food there is average. They really don't have a big selection, and what they have is good, just not amazing. (you go to world showcase or AK for amazing) its just down home, comfort food.
Of course, if you go, you HAVE TO get the Giant S'more. It's to die for.
The food in the Sci Fi was not so great. I only ate there once and might have had a bad experience, but it was bad enough to not warrant another visit. The atmosphere in there was cool though.
Final Score....Go to prime time....so much fun and good smores.:slurp:
