The best way to visit this district is on foot. Once you get tired of Khal al Khalili, I recomend a stroll to the citadel. It shouldn't take you more than an hour.
Cairo's architecture is nothing exceptional. There are a few great mosques, some nice churches, and other interesting buildings. But I won't dedicate much space to the architecture of this city, I think local people are more interesting.
