For a taste of typical Roman-Jewish cooking, head to Via Portico d'Ottavia and Nonna Betta, a small tunnel of a trattoria serving traditional kosher food and local favourites such as carciofo alla guidia (crisp fried artichoke) and fried mozzarella.
Several weekday lunch menus are available, including a €15 option that gets you carciofo, pasta cacio e pepe (with pecorino and black pepper) and a glass of wine.
