JAKARTA — As night falls, groups of twenty-somethings gather at a trendy hangout, chatting at tables laden with beer, iced coffee and nachos. Some couples cuddle over chocolate pudding, while others groove to music on their iPhones.

The nightspot has live bands, Wi-Fi and a growing clientele.

It also has a familiar green-and-orange sign hanging overhead: 7-Eleven.

“It’s a new concept of hanging out,” said Oka Dharmawan, 21, an engineering student who meets friends at 7-Eleven almost every night to log onto the wireless hot spot and drink Slurpees.

Ten years ago, young people in Indonesia gathered at street-side food stalls called warung to hang out and gossip. But with rapid economic growth has come social change.
