Colorado Residents REJOICE! Shake Shack has finally arrived in the mile-high city and they brought with them an EXCLUSIVE burger on their menu available only in Colorado locations! The ☆Green Chile CheddarShack Burger☆! This regional offering includes shredded white cheddar, green chiles and scallions. I got mine with DOUBLE patties AND bacon!
