Topkapi Palace: you kind of have to go

Just like the Forbidden City in Beijing, you can't go to Istanbul without a visit to Topkapi Palace, which used to be the primary residence of the Ottoman Sultans.  I was impressed with the simply elegant architecture (no where near as showy as Chinese palaces) but not so impressed with the typo on their audio guide brochure.  As the main attraction, you think they'd get their materials spell checked.  And this is coming from a girl who was in ESL.
