Drogueria Sarra

This art nouveau pharmacy is short on drugs but long on design. Founded by a Catalan apothecary in 1874, it was built in the elaborate modernist style universally favored by 19th-century pharmacies. The carved wooden racks and shelves backed by murals painted on glass are especially ornate, and the ceramic apothecary jars, though probably empty, are colorfully painted. Also known as La Reunión (note the inscription on the wall behind the counter), this pharmacy was a famous meeting place, a sort of informal neighborhood clubhouse. COST: Free. Weekdays 9-5.
