7 Northumberland Ave, London WC2N 5BY https://www.50kalo.it/ciro__salvo.php Food: £40, Drinks: £27 by Derick RethansFor tonight's meal, we walked to 50 Kalò, a busy restaurant just off Trafalgar Square, and situated in The Grand Hotel. 50 Kalò is a pizza restaurant and an off-shoot of their original Naples-based restaurant. When we got there, we were quickly seated at a small table, with my chair nearly touching a chair on the table behind me. I selected a Prosciutto Cotto—roasted ham on a white base, with shavings of aged Parmesan. The pizza crust was slightly toasted and lovely and chewy, but in my opinion, the base could have been a little crispier.
