A downtown staple for 33 years, Seamus McCaffrey’s attracts a crowd that reflects the changing neighborhood it inhabits: city and county employees, upwardly mobile loft-dwellers and service-industry workers. In fact, Seamus is your favorite downtown bartender’s favorite bar. It also has a tough-to-beat selection of Scotch and Irish whiskey, traditional Irish fare such as Shepherd’s Pie and fish chips, and live music on the weekends (when it can get crowded in here). And don’t miss the bar’s flagship festivity: its raucous annual St. Patrick’s Day street party, when Monroe is closed off and the sweet smell of Guinness wafts for blocks.
