License No. 1 is an underground speakeasy-style cocktail lounge located in the basement of Hotel Boulderado in downtown Boulder, a tribute to the elegant charm of the early 20th century. When Hotel Boulderado opened its doors in 1909, the City of Boulder was dry, having outlawed the sale of spirits within city limits in 1907. In 1969, one of the first legal licenses to serve hard liquor in a restaurant was issued to the bar located in the basement of Hotel Boulderado.

Today License No. 1 continues with the very same liquor license first issued in 1969. Step back in time with classic, handcrafted libations, chef-prepared small plates, and a lively atmosphere. The venue features live music and special events every Wednesday through Saturday.
