I've already seen these Churches, being a Bay Area native myself. In fact, my parents used to make me attend one with them prior to my conversion to Orthodoxy when I was 15. It also hosted a private school for grades K-8th grade. I went there from 6-8th grade. They used to have coffee machines in the front hall along with a small bakery with scones and the like. It also had a ton of PowerPoints and big technology.
Apart from making a lot of friends from the school who I'm still friends with today, it wasn't a very pleasant experience for my family and I. It was VERY oriented toward the wealthy, and my family was kind of shunned since we had less money and the only reason I was able to attend the school was because my dad was employed there and all staff kids got free tuition. The clergy was also a bit corrupt. Very cliche-ran like a high-school. They once fired an employee for something she confided in one of the pastors, and one girl I was friends with wouldn't talk to me anymore because her dad--one of the pastors--told her my family and I was tainted by "generational sin" because my parents weren't married when they had me.
These hipster Churches are just a way of appealing to the wealthy elite. True Christianity will hardly be found in them.
