We may not have the international franchise 7- Eleven store but we have its local equivalent in Phnom Penh. It is called the 6-Eleven. Like all convenience stores elsewhere, it is usually open 24hrs a day and has stocks of all sorts of canned juices and sodas, bottled water, snacks, and other everyday sundries.
It has almost everything that a 7-11 store has. Except that the 6-Eleven store probably opens an hour earlier than a 7-Eleven store. LOL.
