Banca Italian eats in an old NatWest

Swapping glitch for glitz, this old NatWest has been transformed by the Roka peeps into a marble-floored, chandeliered resto. They've kept the safety deposit boxes and vault door, but as with functioning NatWest branches the only other hint of mint is found in the lobster & peach salad, which accompanies other Northern Italian such as crispy courgette flowers stuffed with prawns, and roast milk-fed lamb & piglet belly.
