Osteria Ragno d'Oro is an amazing restaurant in Rome and in my opinion one of the best I've ever tried! It's located in the Prati neighbourhood, not far from the Vatican (around 10/15 minutes walk). It's a charming restaurant offering a lively and fun atmosphere, the staff is very friendly :)

It has one of the best Carbonaras in Rome and I'd recommend to also try the "Carciofo alla Giudea", which is fried artichoke, typical of the Roman cuisine.
