Kho Khaeng's Mahidol Road branch is a Thai drinking spot that keeps going long after most bars close. It's listed as open until 4am. There's an open-air area, an indoor room and private karaoke rooms, so it suits groups out for a long night. It's firmly aimed at a local crowd, south of the Old City on the ring road. It's one of the few places to know about if you're still out after midnight.
