"weekly Palo Alto OpenCoffee Club on Tuesday between 830-100 at Deuce France in the Town & Country Village close to the intersection of El Camino Real & Embarcadero."

It's open to anyone (hence opencoffee) so no need for invitation. You just turn up and enjoy. The first one in London drew 120 people during the 2 hours, completely overunning the starbucks where it took place. I hope Palo Alto will be the same.
