Kevin Morrison wants to fill Denver International Airport guests with Tacos Tequila Whiskey before their next departure. This month, Tacos Tequila Whiskey opened its first DIA location in Concourse A near Gate A18. Morrison is working with Greenwood Village-based airport concessionaire Skyport Hospitality to operate the fast-casual Mexican restaurant. “We had just lost an airport proposal four weeks prior, and I felt rejected and down when [Skyport] first called,” Morrison said.
