Dublin House Inc   

This long, narrow bar is an Upper West Side staple whose Guinness pints have fueled a fair share of hookups, breakups, fights, reunions and controlled-substance use. During the day, a shaft of light from the street streams in and you can see the ghosts of a thousand drunken nights cast on the tiled floor, but the afternoon regulars here tend not to be observant types. After dark, the bar fills with college kids and strange characters -- about the usual crowd for a good dive bar. The wood paneling imparts a faintly unsavory vibe, like a refinished basement from a 1970s horror film, or a Fiona Apple video. The open back room allows for debauchery by larger groups.
