This place is a must-do for all our Disney visits.
In the old days of the 50's Prime Time Cafe, there was much, much more interaction with the guests. In fact, I can remember about 8 years ago, my BF got in "big trouble" for not eating his crusts, so our Aunt/server made him stand facing the wall, with the tip of his nose touching the wall. It was hilarious. Because he was a good sport, some of the other servers got into the action as well, yelling at him for elbows on the table, etc.
The past few times we've eaten there, our servers just weren't too "into it". We were just a little disappointed, but the food and atmosphere more than made up for it.
