Duffy's Shamrock Bar was opened in the 1950s at 1645 Tremont Place and was a Denver institution into the 21st century. It later moved a block over to 1635 Court Place. Denver weekly paper Westword??wrote in 2002 that Duffy's felt "like an East Coast diner, a down-home cookery or a good ol'-fashioned Irish pub, where waitresses offer patience and sympathetic smiles to those who've had one too many Guinnesses. The look is lived-in, not dingy; the food inexpensive, not cheap."??The building it occupied was built in 1910 and is still standing at 1635 Court Place. Duffy's closed in 2006.
