Sandrine’s Bistro and the Harvard Square Business Association are joining forces yet again to celebrate the storming of the Bastille. On Sunday, July 17th, Harvard Square will play host to a celebration from 3:00 to 10:00pm that’ll include music, dancing, drinking and dining. Chef Raymond Ost, who just so happens to be of Alsatian birth, will delight patrons with some high end street eats al la francais with a little help from his friends at Chez Henri. He’ll also be offering a special three-course prix fixe for $25 in the restaurant both on the 17th and Thursday, July 14th. And, just in case that wasn’t enough fancy French fun for you, there’ll also be the traditional waiter’s race, local artisans presenting their wares and an international beer garden. Check out the full details on the celebration here and then make you Bastille Day plans.
