Mientus goes from strength to strength, flying the flag for menswear designers at the cutting edge of fashion. Quirky-classic staples from Paul Smith share retail space with natty argyle scarves and jackets by John Varvatos and Gucci. The selection of tortoiseshell-rimmed glasses is also worth checking out. If lugging purchases around the city afterwards seems too much like hard work, arrange for the store's driver to deliver them to your hotel. Simple.
