PHILADELPHIA (CBS) – Have a milkshake, donate to disaster relief efforts. At Shake Shack, you can do both.

The Rittenhouse Square burger joint is hosting a week-long fundraiser for the American Red Cross to help those affected by Hurricane Sandy.

Now through November 11th, guests can order a “Rally Shake” inspired by New York City’s Black & White cookie, and $2 of the $5.50 price tag will go to the Red Cross.
