Being the younger sibling has its benefits: you get more attention and less pressure, partying nonstop while your brother takes on the terrible responsibility of having the fate of every single British citizen placed in his all-powerful hands. Sort of. For a second-born resto with top-notch credentials, find your way to Polpetto.
Soft-opening today, Polpetto's "a tiny version" of celebrated big bro Polpo, similarly serving up Venetian-style tapas in a small Soho spot whose industrial, brick-walled look's augmented with hand-made zinc tables, salvaged 19th-Century brass light fittings, and mirrors crafted from reclaimed church windows, so you can check both hair and eternal soul. Small meat treats come in the form of grilled sliced flank steak w/ white truffle cream, spicy pork & fennel polpette (lil' balls), and wine-marinaded pigeon saltimbocca -- the more delicious Londoners find it, the more silent Trafalgar Square will grow. For oceanistas, fish sees crispy soft shell crab in Parmesan batter & fennel salad, plus marinated sardines w/ pine nuts & raisins, and cuttlefish in its own ink (how's that defense mechanism now, cuttlefish?).
For the most meager of appetites/those who like many bites of tiny things, there's also "cicheti": intensely flavousrome poppers like smoked swordfish w/ lemon & dill ricotta, Polpetti (baby octopus), and a meatball packed with porcini & duck -- who was having the time of his life, 'till his brother caught him goose-stepping into a party.
