Neapolitan or sourdough, crisp or stretchy, classical or loopy topped? Pizza is a big deal out there, whatever your fancy. For our fetching five we've roamed the field, ignoring the chains (Croma and Pizza Express) and the big Italian restaurants, all of whose ovens produce some great examples. We've had to leave out some of the great street food operators, such as Wood, Fire and Smoke, because they lack a permanent home. A newcomer to the chart is the daring to be different Great British Pizza Co. This means no place for perennial wild card Crazy Pedro's. But we still love it, especially at 4am!
