Excellent club and lovely people

My favorite club in SF! The staff is always nice, they have great line ups and the sound is just amazing :)

I have always had a great experience at Halcyon. It took a while for people in SF to discover it - my first show there for Jonas Rathsman was almost empty - but once it caught on it became the best place to enjoy music. It has a great sound system for being so small; I heard they installed Dolby speakers in the last year. The lights are modest but effective. It is a smaller than normal venue for sure but that has made for a really great experience. Its so fun getting an intimate show with DJs like Nora en Pure, Kyle Watson, and legend Pete Tong.According to other people on this thread, pocket thefts have been growing so keep your belongings safe. As for the staff, theyve always been fairly chill to me. Curt sometimes but hey dealing with show-goers isnt always easy :) Im looking forward to returning.

Greatest Club in SF!!! Amazing sound and service :)

Adam Beyer last night: everything was perfect except for they totally oversold the place. It was insanely crowded. Just for that, Ill seriously reconsider ever going again. That was ridiculous.

An amazing Venue with amazing sound and lights.Gets you close to true sound with the sphere created.Combine this with just one of a kind lighting effect and its a great scene.

Halcyon is a participant in a scam – I bought tickets to a Boiler Room show at the Halycon but eventually found out it was deceptively advertised and branded under the Boiler Room name, but not an official Boiler Room event.The event description was purposely vague as well. Completely unethical and irresponsible.

The acoustics here is incredible.

Really enjoy this space. Open super late and usually host to good djs and fun peeps. DJ booth is like a space ship so get ready to get blasted! :D

Depending on the benchmark u have.Halcyons setup is minimal. Love the LED lights on stage. The ceiling is high gives volume feeling. Sound system is on par w super clubs. I would go again for good shows here.

Cell phone stolen, multiple covers found in trash can same night. Watch your cell phones!

A kind of classy electronic scene. The atmosphere is less dance, and more socialize; you can talk without having to scream. They also have a VIP section behind the DJ, which is unusual for SF. After a point in the night when it starts getting less crowded nobody really seems to care if you go in there.

Reasonably nice venue, with reasonable ticket prices. I went to Halcyon SF on November 10th, 2018, to see Oliver Koletzki. After leaving my jacket in a corner near the coat check, to be picked up later, I found it had gone missing only moments later. Sure enough, at the end of the show, I asked at the coat check and my jacket was in their lost-and-found. The woman working the counter then CHARGED ME money to recover my jacket from their so-called lost-and-found.I left Halcyon feeling cheated; I will not be coming back here.

Cabaret license = late late hours, which is a huge bonus. Good layout but needs better more creative lighting to make up for lack of other rooms. Sound is decent but not spectacular when compared to other clubs.

Really enjoy this space. Open super late and usually host to good djs and fun peeps. DJ booth is like a space ship so get ready to get blasted! :D

Great vibes! Great staff! Good drinks! Good music!

This place is most awesome if you are into the rave/trance/electric dance scene. The strobe lights themselves get you in that dizzy headspace that only raves get you into

Nice club in SF

The staff was not doing enough to eject people who were smoking, and they were on too many occasions. Despite complaints to the security staff, the smokers were allowed to stay. Also the sound system was not up to the standards. The DJ was not happy how the volume would fluctuate on its own. Not going back there again.

Interestingly lit venue with plenty of room to stand and dance. Quick bar service and good acoustics.

The girls at the front desk were the most pleasant and understanding! Not to mention how great the music was!

Great night club, way to dark, but unfortunately that is the current them now a days

Good music, full of gangsters.

Nice club that what I need

Too crowded. Had no room to dance to miguel migs. They refused to open the upstairs.

Nice crowd, good vibe, needs a better sound system .. void or function one ... please !

Awesome place to chill and dance! Unpretentious

Hands down. Halcyon knows how to party

Sick party @Halcyon!!! #love

We got into the club at 02:45, paid $10 entrance fee, just to find out that they were closing and did not sell drinks anymore. Someone needs to edit the details that club closes at 03:00

Great intimate club for electronic music

Warehouse-style club with focus on music

Terrible cocktails

Amazing sound and hot girls!

Loved the place and music

The underground spot for me.

Slow service
