Polpo
41 Beak Street, W1 (020 7734 4479)
Distressed plasterwork, an imported tin ceiling and ancient carbon filament light bulbs bring old-world charm to Polpo, set up in an 18th century building where Venetian painter Canaletto once lived. Only open a fortnight and already buzzing with popularity, there are two sittings for dinner (6pm and 9pm) and diners turning up for their piccolo — Italian for miniature — plates are close-packed. It could feel like sardine hell, but doesn't, because everyone swaps ordering tips — crucial when everything on this menu looks delicious. It's all small plates divided into meat, fish, breads, vegetables and salad, desserts, and cicchetti and crostini — the latter are the (very) small plates which range from £1-£2.10.
