You may know the frenzy of opening a restaurant. Now multiply that by two.

Shake Shack is opening its University City location (32d and Chestnut Streets) on Friday, Oct. 11. And now know that the King of Prussia location - a new building, complete with solar panels, on Mall Boulevard behind the mall - is opening Monday, Oct. 21.

The UCity location will partner with Schuylkill Banks - the riverside-beautification group. The company will donate 5 percent of sales of its Liberty Shell "concrete" dessert (vanilla custard, Termini Bros. cannoli shell, strawberry puree and lemon ricotta).

KoP's partner charity is New Leash on Life, which pairs at-risk shelter dogs with prison inmates. KoP's concrete lineup is the Liberty Shell; the Valley Forge Freeze (chocolate custard, caramel sauce, cheesecake blondie, chocolate sprinkles and sea salt); and the Peanut Gallery (vanilla custard, peanut butter sauce, marshmallow sauce and shattered sugar cone cookie).

The Peanut Gallery concrete, incidentally, was created by the Berger family of Bryn Mawr, which won the task at an auction during the Great Chefs Event.
