Fodor's Expert Review Hong Ren Tang Pharmacy

This traditional family-run drug store has been operating here for more than 70 years. Inside, arcane displays and cabinets are stocked with thousands of herbs and other, more exotic items like antler and dried seahorses—all used to concoct Chinese medicines. Look for the English-speaking counter for foreign customers. This northern stretch of Zhongshan Lu is good for antiques, jade-carving, and other traditional businesses.
