Since Ada died in 2009, her son Sergio has been the sole waitstaff of this five-table hole in the wall called Alfredo e Ada (Via dei Bachi Nuovi 14, Tel 06 687 8842). Reservations are recommended because of the space constraints, but it is all worth the hassle. There is no menu, but nonna Lucia will serve you whatever she has made for the day along with a carafe of house wine. The food is authentic and homemade with no frills other than the flavors you can only find in an Italian grandmother’s kitchen. A great break from the large touristy joints in Rome.
