Shake Shack is opening a new Bay Area location. Shake Shack at the Westfield Valley Fair will open at 11 a.m. Tuesday. Park close to the Bloomingdale’s if you want to be close to the burger spot. The patio will be open for socially distanced dining and you can grab a burger and fries (they are delicious) to go. If you need some incentive to head out tomorrow on opening day Shake Shack will donate a meal to the Boys & Girls Clubs of Silicon Valley for every order placed on opening day only.
