Twansburger
Smashburgers from the La Diabla team, now in a permanent home inside Onefold in Uptown. We have not eaten here, so this is not a review.
Inside Onefold, 1420 E. 18th Ave., Denver
On Our List. This is not a review.
Axios Denver's Oct. 21, 2026 list says Twansburger, the smashburger operation behind La Diabla, has relocated to a permanent home inside Onefold in Uptown. Westword's Oct. 17 roundup said the soft opening at Onefold on 18th Avenue had been revealed and called the move a work in progress. That story did not print hours.
Twansburger's site prints 1420 E. 18th Ave., Denver, CO 80218. Onefold's Uptown page uses the same address for Onefold. Those pages do not give a clear set of Twansburger hours, so none are listed here.
We have not eaten here. There is no score.
