"This bakery, situated right on Campo de Fiori (check out the market, which still sells some of the most beautiful produce from Lazio’s hills and fields – and the hooded statue of Giordano Bruno just outside , on the site where he was burned at the stake), has been baking Rome’s ‘other’ pizza (very very long pizza al taglio, thicker oily base, sold piping hot by the slice for next to nothing) since 1819.
Other than the ultra-convenient and romantic location, the only reason to go is pizza al taglio – have the classic ‘bianca’ (potato & rosemary), ‘rosso’ (tomato & oregano), and in fig season (September-October), prosciutto & fig. Eat on the hoof in the piazza outside." - Evening Standard
