Re: a friend is going to egypt, what to tell them to look for?
In Cairo the El Ashrey and and KM shops are a must. Outside of that I'd suggest getting all the Nakhla naturally flavoured black moassel they don't export and all the stuff in the Prince natural line. I have a post floating here with a bunch of info on great places to visit.
Still, the best thing to do is head to the Southern half of the country and get all the regional tombac and moassels that never make it out of the country. Also, the South is cheaper, less crowded and quite beautiful and represents to me the best of the country.
Our member The Egyptian is in Cairo and doudtlessly could point you to a bunch of stuff as well.
