From the website:
"The Cooper Lounge pays homage to the era of chic cocktail lounges. Skilled bartenders serve a collection of perfectly prepared libations and the extensive wine list is certain to please. Situated in the mezzanine of Denver Union Station, the lounge offers inspiring views of vibrant downtown Denver seen through soaring 28 foot high cast-iron windows on one side and the panorama of the Great Hall on the other."
