Since it opened in 2008, Westminster’s Orchard Town Center has brought an AMC multiplex, REI store and J.C. Penny, among dozens of other retailers and restaurants, to 1.2 million square feet of outdoor mall space near Interstate 25 and 144th Avenue. And now, you can add goat yoga and roller disco to that list. “This is where Orchard is heading in the future: to be known for entertainment instead of just shopping,” said Taylor Alvey, vice president of leasing for Vestar, which owns and operates Orchard Town Center.
