Neergaard Pharmacies is one of Park Slope's oldest institutions and you have only to see its classic, neon-sign lit exterior to know that the place hasn't lost any of its old-school charm: it even has a mechanical pony ride in front of the entrance. It's open 24 hours and stocks hard to find items at affordable prices and has been run by three generations of the same family, who pride themselves on providing Park Slope and its residents with quality care and service.
