High Tea is not "one venue, one lineup, done." At their Festeaval editions, the Milky Way becomes a mini-festival with six areas. That means: you build your own route, from full drum & bass sets to a quieter space, and back into the crowds without feeling like you're missing anything. The format is intentionally broad: DJ sets, live acts, as well as cinema, exhibits, games and interactive things in between.
The big, recent milestone is the Indoor Festeaval 2026: a daytime rave on saturday, march 28, 2026 (15:00-23:00), heralded as the edition in which High Tea presented their 10th anniversary celebrates. For Amsterdam, this is typically one of those events that immediately attracts two types of people: the regular DnB floor dwellers and the curious who normally just "check it out" but then stay until closing time anyway.

It's not a club night with extras; it's an indoor festival where drum & bass remains the backbone.
High Tea additionally does separate specials in the same atmosphere. Example: High Tea Amsterdam w/ Hedex at the Milky Way (June 13, 2025, 21:00-06:00, 16+), a typical "big name + full night" edition.
Practical: the Indoor Festeaval will take place in the Galaxy (Lijnbaansgracht 234A). If you go for the "festival feel," grab the 6-area edition; if you come purely for a headliner night, check out the separate High Tea nights.
