Rock Bottom Brewery closes after 35 years in downtown Denver

Rock Bottom Brewery’s original Denver location on 16th Street has permanently closed after 35 years, ending one of the city’s earliest microbrewery stories with a small printed notice on the front doors. The shutdown leaves the corner at 16th and Curtis without a brewpub that once helped define the block and gave downtown Denver one of its first real craft-beer anchors.

Founded in 1991 by Boulder restaurateur Frank Day, Rock Bottom opened on the ground floor of what was then the Prudential building, with a name that reportedly nodded to Prudential’s “Get a piece of the rock” slogan. At the time, the Denver beer scene was still taking shape, and Rock Bottom quickly became part of the early wave that normalized craft beer in an urban entertainment district. It was also an early rival to Wynkoop Brewing Co., which opened in 1988 and is widely recognized as Denver’s first brewpub.

The closure lands with extra weight because Rock Bottom was never just a single restaurant. Rock Bottom Restaurants, Inc. became the first publicly traded restaurant-brewery company in the United States, then was taken private in a 1999 management buyout. At one point, the company operated about 10 Rock Bottom Brewery locations along with other brands, including Old Chicago and ChopHouse. That growth turned an early local pioneer into something closer to a multi-state chain, and the downtown Denver outpost gradually became part of a much bigger corporate footprint.

Frank Day’s influence on Colorado hospitality ran far beyond one brewery. He founded Concept Restaurants in 1976 and later owned or operated more than 80 hospitality businesses, including Old Chicago, the Walnut Brewery, and Rock Bottom Restaurants, Inc. Day died in 2025, and John Hickenlooper, in a 2025 interview, summed up Day’s role in the city’s beer boom bluntly: “took every one of our ideas and made them so much better.”

The downtown closure comes amid changing conditions in downtown Denver and broader financial pressure on hospitality businesses. Rock Bottom’s disappearance from the Sixteenth Street Mall, now part of Independence Plaza’s changing landscape, reads less like a standalone restaurant closing than the fading of a first-generation brewpub era. Other Rock Bottom locations in the metro area were still open, but the original on 16th Street had reached the end of the run that helped launch Denver beer culture in the first place.
