About Dublin
City overview
Dublin sits on the River Liffey where Georgian squares, Viking-medieval lanes, literary pubs, Trinity College, the Liberties, Temple Bar, Smithfield, and St Stephen's Green make a compact city-center route. The city works best on foot, with DART coastal trains and Luas trams extending the map to Howth, Dun Laoghaire, and the docklands.
Food & drink
Dublin food is pub, market, and coast-fed: a full Irish breakfast plates sausage, bacon, eggs, pudding, beans, and tomato, Irish stew slow-cooks lamb or mutton with potatoes, seafood chowder uses Atlantic shellfish, and boxty turns potato into pancakes. The Brazen Head, Moore Street, George's Street Arcade, Temple Bar Food Market, Capel Street, and Howth seafood stops add soda bread, fish and chips, oysters, and Guinness pours.
