We were at La Nonna recently.  We had Pan Brusquieta, Canelones Rossini, Fettuccine all amatricana and a very good bottle of wine for 25.50 euros plus tip.

At my request they added some more chilli to the pasta and made it almost "Arrabiata"

The result was fair if very over sauced.  The menu said the canelones should have had Bechamel Sauce.  It came with tomato sauce and the canelones themselves were very poor. 

I would say not worth going back.
