Not only is this shop Beverly Hills' only environmentally friendly CO2 dry cleaners, Nonpareil Cleaners also gives us a relevant vocabulary lesson -- the brand name means "having no equal, peerless." Nonpareil has been in business since 1945. The shop's chemical-free liquid CO2 process is environmentally safe. In addition to Beverly Hills, Nonpareil Cleaners' coverage area consists of Bel-Air, West L.A., Santa Monica and Malibu. The shop offers alterations, drapery cleaning and leather cleaning.
