Shake Shack - the burger chain that opened last summer at 20th and Sansom Streets - is indeed opening in University City - taking space at Drexel at 3200 Chestnut St.

A spokesman confirmed this to me. Timeline is late summer/early fall.

Shake Shack will join another New York-rooted operation there, Joe Coffee Bar.

This means competition for Bobby's Burger Palace at 40th and Chestnut on Penn's campus, as well as Drexel hangouts Spencer's ETA Burger at 34th and Powelton and the Spotburgers truck at 33d and Arch. To which Spotburgers says on Twitter: "BRING IT ON!!!"
