Inside, the space is contemporary-chic, as though HGTV had just wrapped filming there (maybe Color Splash or Secrets from a Stylist?): There are bright white chairs, tables topped with lavender daisies, and colorful art on the walls. Outside, you can relax on an equally inviting patio space -- with umbrellas to hide you from the summer sun. You order from a counter at Astor House, but that doesn't mean that service isn't attentive -- whether in refilling your water glass from an ever-ready pitcher or kindly escorting the occasional stray fly out the front door. Add all this to free WiFi, and you could easily spend an afternoon.
