In the heart of Rome you can find a restaurant a very nice restaurant where you can savour the typical Roman cooking.
For this reason I enclose the name of the plates in Italian.
You also might be disappointed in ordering cappuccino, ketchup and pasta with meatballs and discovering they do not serve them!
To tell you the truth they also wrote on the menu they do not offer your international variations but if you want to taste something typical it is absolutely worth a try.
So far I have always been to the restaurant located in Piazza dei Quiriti, 4 but here on their website you can find also the address of the one in Testaccio district.
I also would like to add that, so far, also the service has been to the top!
