Cous Cous in Cherry Hill....just off of 295. Haven't been there recently (since we moved away) but it used to be pretty good. I believe it's the same owners as Norma's Mediterranean which is next door and also good.
The only Moroccan restaurant I know of is Marakesh in Parsippany. I've never been so can't comment one way or another. Reviews on other sites are pretty positive.
