St. Patrick’s Day is on a Saturday this year — need we say more? Though other neighborhoods try, none do debauchery quite as effectively as the Marina, where green-clad partiers will find a classic pub crawl in full swing during Civic Center’s more family-friendly festival. The fun begins at The Dorian, but pro drinkers will wind their way through other Marina mainstays, including Palm House, Brixton and Blue Light.
