A fun and funky bar whose name stands for "naturale, organico, alimento, umano" (natural, organic, humane, food) and is a play on the English "know-how."; There's an insider vibe – two of the owners are superstar pizzaiolo Gabriele Bonci and brewmaster Teo Musso – but the place is totally mellow, with friendly staff and painted, mismatched tables and chairs.
