"Yes, Shake Shack is a chain, but at the end of the day, Shake Shack is reliably good. And there’s also a location conveniently located in the Willis Tower. So if being 1,353 feet in the sky leads to jelly legs and/or vertigo, regain your composure with a burger (or chicken sandwich, or hot dog, or crinkle cut fries, or milkshake)." - john ringor
