The city’s Irish watering holes have been wildly successful subscribing to a simple McPub formula: a preponderance of shining brass and wood paneling, choice of Guinness and Budweiser on tap, and obligatory, only-in-America fare like nachos. O’Flaherty’s is no exception to this predictable facsimile of old-country ambience, but they do it bigger and better than most. A maze of cozy rooms with library-lined walls and inviting fireplaces carry literary, Alistair Cooke-style pretensions, while an enormous rectangular bar betrays patrons’ true passion—an array of tap beers available by the pitcher. There’s also sturdy fare like Murphy’s stout pie and a warming Irish coffee that arrives with a shot of whiskey and a dollop of whipped cream; a pool table, darts board, and outdoor garden provide plenty of diversion. Not surprisingly, O’Flaherty’s draws a line of rowdies down Restaurant Row on St. Patrick’s Day, but a Sunday-afternoon visit can be utterly enjoyable and surprisingly atmospheric.
