Make no mistake, Sultan's Tent is only here for gimmicky entertainment and ambience, not for the food. The bellydancers are entertaining, but they lose their novelty pretty quickly (more amusing are the people dancing stiffly with them. :D)
I came here for a friend's birthday and ordered the following:
Harira: A good and hearty soup. I like it.
Maftoul: nice and crispy! I liked this. A tad on the greasy side though.
Couscous royale: The sausages were undercooked and had a gross texture. The meat also tasted like it may have gone bad. Lastly, I've never been a fan of tagine (I should've remembered that before ordering it!)
Moroccan treats: Dry as heck.
Dinner came out to about $50 per person. Note that there are a bunch of "upgrade/upsell" options that they try to push on you.
The only really awesome part of the meal was that for my friend's birthday cake, they brought out a dessert in the shape of a fez. A-MAZE-ING. (the tassel was made of chocolate)
