Whataburger may soon open its first metro Denver location in decades, with the chain submitting an application for land in Douglas County.
The national restaurant chain — headquartered and based in San Antonio, Texas — submitted a Castle Rock land use application in November 2025, according to a site development plan. If approved, the restaurant would be constructed near the Outlets at Castle Rock.
Whataburger operates nine restaurants in southern Colorado, according to the company’s website. That includes Colorado Springs, Fountain, Monument and Pueblo.
If opened, the new Castle Rock location would be Whataburger’s first in the Denver area in decades. The fast food restaurant would be open 24 hours a day, seven days a week, according to the site development plan.
The vacant 1.53-acre lot sits next to a Chipotle and across from Sam’s Club, just down Promenade Parkway from the outlet mall, according to Douglas County property records. It was valued at $786,038 in 2025 and sold in March to the Promenade at Castle Rock for $1.5 million, records show.
This is a developing story.
