There’s an Old World European feel to the patio at Poste, starting with an arched carved-marble entryway from the 1840s. The outdoor space, framed by soaring limestone walls, is home to a collection of seed beds and potted plants. Bartenders use the herbs for infusing liqueurs and muddling into cocktails. Weekdays from 4 to 7, the courtyard is chockablock with young professionals looking for a bargain: Truffle fries, wine, and beer are $5.
