Made my second trip to Marrakech while in Vegas during the first week of May. We went on a Monday night and the place was dead! Almost too dead. But the food was plentiful and delicious, although there were a few gaps in between courses that could have been shorter since they weren't really that busy.
The belly dancer was entertaining and not too pushy, which I liked. Sometimes they can be a pain in the ass trying to coax you out of your seat to dance with them. For the fixed price of about $40 per person, you really can't go wrong here. You will leave stuffed and feel as though you got your money's worth. For a first time visitor to a Moroccan restaurant I would highly recommend Marrakesh; if you've been before and are looking to try a different place, I would still recommend but it won't be anything you haven't seen or tasted before.
