Over-18s Halloween party at 331 Old Street with a sexy dress code for ladies and smart casual for guys.
331 Old St. Bar & Club is throwing a Haunted Halloween Basement Party on Saturday 31 October, and it's one of those nights that takes over the whole place. The party runs from midnight on Halloween night right through to 3am on Sunday morning, so it's a proper late one. They've billed it as 'London's Biggest Halloween Party' and 'London's Biggest Party Ever', and it's not just a one-off: the club runs these every Friday and Saturday night, with the action spread across the ground floor bar and the basement.
If you're planning on heading down, there are a few things to keep in mind before you leave the house. There's a strictly enforced dress code: ladies, sexy; guys, smart casual. That means no hats, no hoods, no sportswear and no shorts, so it's worth double-checking your outfit before you set off. It's an over-18s night, and they're firm on the ID — no ID means no entry, and you'll need a passport or a driving licence to get through the door.
