The elusive best poured Guinness: a chilled, ruby-colored brew buried deep in a pint glass and crowned with a creamy, frothy head that coats your throat on the way down. Maybe the Irish have fire in their blood because, west of Ireland, finding this heady, alcohol-filled treasure done right is rarer than finding gold at the end of a rainbow. But at the Field, a dollhouse-like Irish pub, you can settle on the outdoor patio (under the shade of an enormous banyan tree) and have a pretty bartender pour you a pint of pure perfection. The Field may not be close to Ireland, but it's certainly close to heaven.
