Interestingly enough I was on the Lululemon site and in their careers section they have a listing for a Noe Valley store - maybe that's what is going in there? As a bona fide Noe Valley lady who loves her Lulu, I would be stoked as hell.Lululemon is a boutique retail chain that sells "technical athletic apparel for yoga, running, dancing, and most other sweaty pursuits." We can't vouch for the job post on the Lululemon site - but given there's a store on Union Street it's plausible one could open here too.
Update (6/24): Still a rumor (emphasis ours):
Thank you for your interest in lululemon athletica. As of now, nothing has been confirmed for a new location in San Francisco. However, if we do decide to open a new location in Noe Valley, it will definitely be posted on our website under 'store finder'.
I hope this information helps!
