I've been here for a few events and while each returning trip makes me less and less in awe of the location it goes without saying that the premise for this event space is intriguing and the space itself is beautiful. You can host a great many event types in here from big parties, concerts, weddings to the more recent type of event I was here for a 360 screenings which combined live theater and watching a movie.
The actual church part is no where near what this venue offers, it has a large area outside as well as a rooftop area all of which are very picturesque and given the right weather can prove to be a very unique experience.
In some of the events I've been to I know of some people that have not had a good time with the staff in here particularly the bouncers and in my experience of trying to host events here I too have come across very sub par customer service. But the serving staff and bartenders have always been friendly.
Overall for an event goer this venue has everything they would want in terms of the exclusivity of drinking in a church but for an event planner I wouldn't recommend Berkeley in terms of how they handle the planning on events.
