Happy Birthday Shake Shack
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.
