Off the bustling Rue Montmartre, this unique concept store is Paris's perfume and skincare central—a must for seekers of that elusive perfect fragrance. After you're installed at the bar (with refreshment), you'll be given a detailed questionnaire on the in-house iPad to pinpoint 5 or 10 scents from 500 niche perfumes that correspond to your deepest self. There's also a super range of European skin-care products, scented candles, and other delicious surprises.
