Found the answer at Steve's site for live entertainment... I forgot about his site. What a great site for information.
Traditional Moroccan music and dance inside Restaurant Marrakesh.
Daily at 12:50, 1:50, 2:50, 5:00, 6:00, 7:00 & 8:10pm
Belly Dancer begins 10 minutes after show begins.
Length of show: 25 minutes
I was just about to post this same question! So, based on PP, a reservation around 7:45 - 8:00 would be best for the last performance. DD6 really wants to see the belly dancer. Great info!
