For some cool dinner shows, you'll have to travel off-site. The closest ones to Universal are Pirates Dinner Adventure and Sleuths. Both are very fun, have great food, and are interactive. Plus they're both off Universal Blvd, so they're a short drive away.
Sleuths is a murder mystery show. In the beginning, you get to mingle with the characters while you get seated and acquainted with the people at the table you will be sharing. The show eventually starts, and someone dies. The PD shows up and explains your role. You try to figure out "whodunit" and can ask a question to any of the characters. It's quite fun, and they have several different "cases", so you may not get the same show twice!
