The Baron's Ultraviolet Uproar

The Baron, of The Baron's Tasting House is turning another old! He only wears black and red, you say? Lies! One day a year he gets hypercolour happy dayglow. It's a sight to be seen. Join us for a celebratory neon speakeasy rave, wearing your irradiated best, for cocktails, crankers, and cutting le rug.

TLDR; it's The Baron's birthday and he wants to party with you.
