Salamis, hams and cheeses are displayed in glass-fronted cupboards at contemporary deli-restaurant Roberta. Start off with antipasti plates loaded with Italian delicacies (creamy burrata, prosciutto di Parma or ricotta-stuffed courgettes) but save room for house-made pastas like spaghetti with (salted fish roe), squid-ink linguine with truffle cream, or triangular filled with spinach and walnuts. No reservations.
