I believe we have only been on one trip where we didn't eat at one of them, but never both in the same trip! 50's used to be a must do every trip, but we have missed the last two trips. It's not that we don't still enjoy it, we have just been there so many times. We did Sci-Fi and really enjoyed it, such a very cool atmosphere and I usually stick with burgers there which are excellent. 50's has as good fried chicken as I have had anywhere.
