Have tried almost all also....Hated Alfredo's- greasy sauce, overcooked pasta
Hostaria DaVittorio's- one year the food was fantastic next year awful...
La Tratorria's was okay,
My favorite was Sole Mare....seems to be at least consistent, don't really need reservations if you go about 5-6.
Tough that we all have our own opinions, you will just have to keep going back each year to form your own!!!!!!
