While both are good choices, I agree with you and would try 50's just for the change. On my last,week long, trip to the world, and on the dining plan I decided to eat every meal at a restaurant that I have never tried before in my 10 annual trips so far. Sci fi and 50's among them. I think like many people, I always went to the same restaurants year after year because not only was it good food but comforting in that you knew what to expect. If you visit WDW often, thats one way you can make each visit new and different. I am not a picky eater and had no regrets. Be daring! Be adventurous!
