Happy Birthday Shake Shack

It might seem hard to believe, but it’s been two years since Shake Shack came to Philly.

Actually, it’ll be two years tomorrow, which is why the Center City Shake Shack will be throwing itself a party, complete with a 1-day-only concrete made with pieces of its birthday cake from Termini Bros.

And lest you forget, tomorrow is also launch day for the Marc Vetri / Shake Shack collaboration burger–the Carbonara Burger–at all Philly-area locations.

The concretes are $4.25 for a half, $6.50 for full-size.
