If you and a couple friends can't agree on what to do this weekend, Playdrome Paintball ( Paintball / Paintball İstanbul / Paintball İstanbul Avrupa Yakası ) over in Bakırköy is an option. Activity venues usually discount for groups and charge standard rates for smaller ones. Weekend slots fill up fast — booking ahead is the smart move, since walk-ins who can't get a spot end up with a ruined afternoon.
