I don't know if you guys experienced the Flea Market in Al Safa Park.
I went there yesterday and it was so much fun. There's lots of stuffs; brand new, and secondhand.
This only happen every first Saturday of the Month. I am recommending this to all of you if you haven't tried this one yet.
You only need to pay the "Gate Entrance" which is 3 Dirhams and just follow the crowd. Oh by the way gates open at past 7am the earlier you go the more great stuffs you will find.
Best of luck!
