This Is Halloween! Club Underground 2 Floor Party

Halloween weekend in Chinatown has a dance floor with a dress code of "anything but street clothes." Club Underground takes over Grand Star Jazz Club on Friday, October 30, for a masquerade ball and costume party that runs across two rooms. If you are sorting through things to do in Los Angeles before the 31st, this is the one built for people who want to dance in costume.

When: Friday, October 30, 2026, 9:30 PM to 1:30 AM Where: Grand Star Jazz Club, 943 North Broadway, Los Angeles, CA 90012 Tickets: $11.33 on DICE Age: 21+

What the night looks like

The flyer bills it as a post-punk, indie, britpop and goth dance party, so expect the soundtrack to lean on moody guitars, new wave and the kind of singalong anthems that fill a floor at midnight. Two rooms means you can move between spaces instead of staying parked in one crowd. The listing does not name a DJ lineup, so treat it as a resident-style club night rather than a headliner show.

A costume contest with prizes is part of the plan, and the masquerade theme gives you an easy excuse to go big with a mask. Show up dressed. Nobody is going to be impressed by a half-effort cat ears situation when the whole point is the look.

Why Grand Star

Grand Star Jazz Club sits on North Broadway in the heart of Chinatown, a neon-lit room with a long history as a small music venue. It suits a Halloween party well: low ceilings, a bit of old-school character and a stage-and-dance-floor setup that keeps the energy close. Among the LA events this weekend and next, it is a compact pick if you would rather skip the giant warehouse crowds.

Practical info

Tickets run $11.33 on DICE, and advance purchase is the way to go on a holiday weekend. This is a 21+ night, so bring a valid ID. Doors and set times beyond the 9:30 PM start are not published, so arrive early if you want first crack at the dance floor and a spot in the costume contest.

Getting there is simple. Chinatown is reachable by the Metro A Line at Chinatown Station, a short walk from the venue, which is the easy call on a night when you will probably be drinking. If you are driving, expect street parking to be tight and plan for a rideshare home instead. Dress in layers you can actually dance in, and consider a mask you can see out of.
