Opened in 1936, in this location since 1949, Bergin's is what some aficionados call an Irish American pub. Known for its shamrock covered walls, smooth Guinness, Irish coffee and hearty Irish menu, Tom Bergins opens its doors at 6 a.m. this year to welcome St. Patty's day revelers. We recommend starting out early; TB's is quite the popular destination for Fairfax district/Miracle Mile locals during happy hour, and they will be full by 8 p.m. or earlier.

Open 8:30 a.m.-2 a.m.

On the 17th, there will be a traditional Irish bagpiper along with Djs and pints of Guinness for $5. Plus, Casey's double-decker bus (complete with mobile pub) will be cruising around the area, making stops at Cole's, Seven Grand, and the Golden Gopher. Reserve a seat for $30.
