Colonial Drug

A unique, family-run business, this dispensing chemist hasn't changed in appearance for decades. These days, though, the emphasis is more on luxurious scents and unguents than bromide and hot-water bottles. In particular, it specialises in hard-to-find perfumes (stocking more than 1,000 fragrances, including Guerlain and Patou), and beautifully packaged scented soaps.
