Encores does one after the Saturday matinee for their three shows. They are usually quite good as Encores tries to pull in someone associated with the original show. (I'm hoping for Ruby Dee, Melba Moore or Sherman Hemsley for "Purlie") The worst part is when people in the audience ask really stupid questions. (Yeah, I know there are no stupid questions, but you have to hear some of the ones these people ask).
Roundabout also does it with their shows.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
