Lal Hardy's Muswell Hill studio is London's most famous, offering a wide range of styles, from mechanical (Collins) to Japanese (Orist) to feminine designs (Zed), which is probably why they've attracted such celebrity customers. It's not as chic as some of the other parlours, but at 20 years old, it's still one of the most dependable.
