Taxis can be wonderful in Cairo. They are affordable, ubiquitous, you don't have to find parking, and you can leave at a moment's notice! Just be ready for a different approach to driving: no lanes, little space between cars and people, barely stopping at lights and stop signs, all compensated for with a lot of honking! Here is a taste of the taxi experience in Cairo.
