Shake Shack opened to a long lines at the Stanford Shopping Center in Palo Alto, CA, on December 15, 2018. A new Shake Shack store was to open at Westfield Valley Fair Mall in Santa Clara, CA, during Spring 2020. The coronavirus pandemic shut down the malls for six months. The San Jose Mercury News announced that Shake Shack would open at Valley Fair Mall this past week. I did a walkthrough on Sunday, 9/27/2020, looking at the new store inside and the promenade outside. The strawberry milkshake was great!
