Jakarta, unlike bangkok, has slightly more restrictive alcohol laws, for instance no 7-11's can sell alcohol.
there is a few duty free shops in town that used to sell to expats, but you needed your passport.
Today i found out that they are only can sell it to you know if you have a diplomatic passport!
I can still get wine and beer at shops, but sadly nothing harder, for the moment! I hope this is a short lived crack down!
