Eater SF says it’s the Summit, a new cafe/living room/place to hang out:
The whole shall be greater than the sum of its parts at ex-Poleng owner Desi Danganan‘s new “third space” concept. And those parts are a counter-serviced, brasserie-inspired menu; an art gallery, Blue Bottle coffee, a pastry program with rotating guest chefs and an event venue all wrapped in a designy space shared with business startup incubator i/o ventures.
Read on for more about the Summit and game changers in six other neighborhoods.

Cool place with some pretty ladies working the counter as well.
looks like they are trying to mimic the now-defunct Canvas Cafe in the Sunset, which isn’t a bad thing.
I don’t quite get the part about it being home to startups and this I/O Ventures thing. Does that mean they’re paying for offices in a cafe? Or what?
It means they are backed by big player Venture Capitalists. Duh
it reads like the swiss army knife of spaces. and not in a good way.
