SAID, antica fabbrica della cioccolata, via Tiburtina 135. This restaurant used to be an old chocolate factory and preserves the original decorations. Very nice ambiance and a delicious buffet for lunch that varies every day and costs €10. A lot of veggie options, some fish and meat; only a few dishes a la carte. There is also a dessert buffet with lots of types of chocolates and chocolate cakes.
