We&#x27;re proud New Yorkers of course, but we also have plenty of respect for the @Kathi Winslow. To celebrate their #WorldSeries apprearance we&#x27;re serving up a special sweet treat at our Chestnut Hill, MA. #ShakeShack. &quot;The Green Monster&quot; is a minted marshmallow crème milkshake, $5.50. Play ball!
