Voor de 8ste keer op rij vindt Amsterdam Halloween plaats op het Westergasterrein in de hoofdstad van Nederland. De Westerunie, Transformatorhal, én de Westerliefde vormen tijdens dit Halloween weekend het toneel van intergalactische Super Helden. Kom dit jaar als Spiderman en hang de hele nacht aan de bar terwijl Captain America de beveiliging een handje helpt. Invisible Man heeft de hele avond zelfservice achter de bar en bij Catwoman is elke vent in een handomdraai ‘whipped’. Lauw biertje? Gelukkig staat Iceman even verderop! Natuurlijk mogen bezoekers ook hun halloween fantasie de vrije loop laten, zolang ze maar verkleed komen. Attend on Facebook
