What first caught my eye as I approached Que Ricoto was the owner, David, standing next to his cart of olive oils and greeting passersby. In a city as big as Madrid, it's rare to have these touches of personality. The wide selection of olive oil-based products that David and his wife sell in their store is just as noteworthy. You'll find a wide array of soaps, lotions, and, of course, oils alongside gourmet sundries and fine Spanish wines. Pick up a bar of the “Why Dark?” chocolate and a few other treats for a picnic in the park.
