It's time for some good old fashioned, frightful fun!

This Halloween, W5 comes alive after dark for an adults-only night of thrills, chills, and twisted science. Step inside if you dare, where experiments take a chilling turn, and shadows stir in unexpected corners.

Enjoy devilish drinks from our licensed bars, let our face-painting artists give you a haunting new look, and test your nerve (and your knowledge) with speed quizzing before surrendering to the beats of our live DJ. And with more eerie surprises yet to be revealed, nothing is ever quite what it seems.

So round up your bravest friends, don your best cape, wings, or wickedly good costume, and get ready for a night where fun and frights go hand in hand.

After dark, W5 is not what you remember. Do you dare to discover what awaits within?
