After decades serving up food, drinks and dancing in the National Western Center’s Livestock Exchange Building, the Denver Stockyard Saloon will close its doors in April after a clash between the restaurant and building owners over renovation plans. Saloon owner and manager Dean Maus announced the closure in a Facebook post and confirmed the news to The Denver Post on Wednesday. Maus said the building’s new owners initially tried to work with him on keeping the saloon open, but negotiations later fell apart and they stopped responding to his messages.
