Rick Steves in Istanbul

Istanbul was the featured city of tonight's PBS re-broadcast from intrepid traveler Rick Steves.
In Chicago, the show was on Channel 20 at 8 p.m., but you can check local listings here on his Website. He brings home that the Turks have a script for the city's tourists: nation created in 1923, Sultans at Topkapi lived in rich sophistication, Istliklal Caddesi is interesting, and Hagia Sofia was the center of Christianity.
Why, as a museum, even after restoration, is Hagia Sofia still in a state of decay inside?
Working at the family dining table here, I just can't bring myself to finish the last nibbles of the loukoumi (locum) that I bought back from an adorable old-fashioned-looking shop in Uskudar. That's a neighborhood on the Asia side of Istanbul where there were many Greeks and Armenians at one time; the ferry ride across the blue sea full of fluorescent jelly fish, the warm sun setting, was really pleasant.
I realized after I got back to the states that the candy box decoration is a church. I thought it was just a clock tower, since there is no cross on it. I didn't recognize the spelling of church, "kulesi," because I only knew it was pronounced KEEleeseh.
