This is most horrible place in San Francisco! Yest...

This is most horrible place in San Francisco! Yesterday I went to event and I was attacked by security people who work at Mezzanine for taking a video of the event from the balcony. Apparently I was in VIP zone taking a video. I was immediately escorted out and told I can not enter the event. After pulling my phone out to record the explanation why I was escorted out security people attacked me, dropped me on a ground and started choking me until I passed out! They took my phone away from me and have not given it back after asking them politely to give it back. PLEASE BE AWARE OF THIS PLACE!
