Optimo Espookio @ Sub Club, 28 Oct

One of the annual highlights of the Scottish clubbing calendar is Optimo's Halloween bash, Espookio. The Optimo regulars are famed for their outlandish dress sense and lack of inhibitions at the best of times, so with the prospect of a competitive fancy-dress contest, the Optimo Halloween Cup, they really pour on the creativity.

Previous years' crowds have included zombies, ninjas, robots and characters from films and cartoons – each year sees the Optimo crew trying to go one better than the last, and as always, JD Twitch and JG Wilkes will be on hand to soundtrack the madness with the genre-busting, eclectic selection which has made Optimo a world-famous name in clubbing. Espookio is sure to be busy, so get down early to make sure you can join in the fun.

With a distinct lack of decent Halloween-themed clubs this year, and the tendency of many fancy-dress parties to err towards the cheesy and embarrassing, Espookio is a well-loved, debauched alternative – no tricks, all treats.
