London is in the throws of a pizza war, with rival factions fighting it out along partisan, increasingly local lines: Detroit style, New York style, Chicago style; Neapolitan, Roman, Tuscan; even London has its own varietal now, spurred on chiefly by the good work of Crisp. But Newington Green’s Bar Etna is a style entirely unto itself — a sort of East London-Philadelphia cross (with a touch of the fashionable ‘New Haven’ variant to it) which creates pies that are sometimes familiar but often surprising: like a spicy spinach curry pizza and one topped with coolea, a West Irish cheese. Created by Ed McIlroy (who also owns The Plimsoll and Tollington’s) and Philadelphian pizza chef Joe Beddia, it is very good, pleasingly original, and just as much fun as its vast, stainless steel bar implies.
