By Shawn Patrick Mar 31, 2021 First Californians in Colorado rejoiced as In-N-Out Burger setup shop in Colorado, now Texans can feel that same joy as Whataburger is coming to the Centennial State as well. A 3,751-square-foot Whataburger restaurant would be built in the InterQuest Marketplace retail complex, east of Interstate 25 and InterQuest Parkway on Colorado Springs' far north side, under a proposal submitted to city government planners. Whataburger's construction would begin in the summer and the restaurant is expected to open this fall, the proposal shows. Whataburger's Colorado Springs restaurant would be built a short distance from In-N-Out Burger, the California-based chain that expanded to the state last year.
