The Monastiraki flea market is the place to be on Sunday when it seems every Athenian is here either buying or selling. You have to get here early because after about 11am the crowd becomes impossible and if you want to take a break there are few tables available at the many cafes and restaurants in the area. You can wander around aimlessly or you can find someone who knows the flea market who can show you around if you are intent on buying something in particular. Much of the flea market is not really a flea market. It is a collection of small shops of which most of them are tourist shops with the same stuff you will find on Adrianou street in the Plaka. These are open normal shop hours and you can come here anytime. But weekends and Sunday in particular is when it is like a third-world flea market with people selling anything from antiques to what you might call useless junk and it goes on forever, beyond Monastiraki and into Thission and Psiri.
