O'Keefe's Tavern is a historic Irish restaurant and pub in Clearwater, Florida, established in 1961 and renowned for its deep local roots and enduring family ownership. It features unique elements like a brick pole that stopped a truck crash into the building and a famously scarred painting in the 'Cedar Room.' The tavern is celebrated for its legendary St. Patrick's Day party, which has grown into one of the largest private celebrations in America.
