Want to take a picnic to the High Line or the nearby Pier 51 at Hudson River Park? Stop at Three Owls Market. A full line of healthy prepared foods might include grab-and-go kale salad slicked with tahini and studded with sunflower seeds. On the opposite spectrum, there are unmissable salted butter chocolate chip cookies and fat chocolate croissants. Or just stay put; the counter-service café has several tables and a bar with a brief list of wine and beer, and breakfast is served all day.
