What is it?

Fountain soda topped with a scoop of Shake Shack's frozen custard, this drink pairs carbonation with a dense, egg-rich dairy base. As the custard starts to melt, it softens the soda and forms a foamy layer at the surface, so the texture changes from fizzy to creamier as you drink. Compared with Shake Shack's shakes and concretes, this option stays looser and more liquid, since the soda does the work of thinning the custard. Soda choice varies by location, and some shops may pair it with seasonal custard flavors. It's served in a standard cup with a straw.
