If you like football it is your chance to watch live at Celcom show at Subang Parade. So many people there and you can see some stalls there selling drinks and food so you don't get hungry. Unless you bring your own food it will be cheaper, I spotted the 100 plus can drink MYR$2 a can.
They will be there until 4am there many cars in the area there. Most people near housing area to walk over there.
