The private-equity owner of the Smashburger chain has launched a new full-service restaurant concept in Denver.

Called Tom’s Urban 24, the casual-dining concept, which debuted on Oct. 31, is open 24 hours and serves breakfast, lunch, dinner and late-night dayparts featuring comfort foods with an “urban culinary twist.”

It was designed by Tom Ryan, founder of the 183-unit Smashburger and a managing partner with the fast-casual burger chain’s parent, Consumer Capital Partners. The Denver-based private equity firm is also working on another concept called Tossa Pizza, with one unit in Boulder, Colo. The firm previously owned the Quiznos chain, which changed hands in a debt-for-equity swap last year.

Tom’s Urban 24, however, is a unique concept that aims to take full advantage of dining needs around the clock, according to Ryan. But don’t call it a diner.

“It’s not a diner. It’s a restaurant and bar with modern comfort foods,” he said. “The adult casual-dining segment is populated by not-so-modern concepts. We wanted to bring a modern approach to everyday eating out.”

At breakfast, for example, served from 5 a.m. to 11 a.m., the menu might include house-made “Pop Tarts,” pastry stuffed with fruit or savory fillings; a breakfast burrito with chorizo and green chile; or pumpkin-spice pancakes with cinnamon-caramel sauce and salted-caramel butter.
