After a visit to the Guinness Storehouse you can have a pint in The Gravity Bar at the top. There’s no better place for it; you get great views across the city. For a drink at night, Dawson Street, parallel to Grafton Street, has a number of sophisticated bars. They change names all the time but there’s Sams Bar, 37 Dawson Street, and Café en Seine, which has beautiful high ceilings and gorgeous interiors. You’ll hear a lot of posh “D4” accents there.
