For us one of the best is Sostanza detto IL TROIA Osteria. Order the  Fiorentina T-bone stick, you

sostanza detto il troia, firenze

will never, ever eat anything as good as this. The restaurant is small and non-descript, but very popular for all the 100% authentique fiorentini. Everything on the meal looked and smelled incredible. We also highly recommend you to eat the butter chicken ( it literally is more than amazing).

Make sure you have reservations or you will wait a long time to get in. Where: Via della Porcellana, 25 r – 50123 Firenze – tel + 30 055 212691
