Sounds like workclub will be cafe-ish, but with a focus on providing a space for mobile workers. (As opposed to normal coffee shops, which still pretend to be just cafes, but in this town are overrun with mobile workers.)
Looking forward to it opening up. There are several other coworking spaces in town now, but they're mostly downtown or in SOMA. This will be a great addition to the mid/upper-Market/Mission area.
