I just came across this initiative today; participating restaurants include Locanda, Delfina, Delarosa, Boulevard and Pinseria Montesacro. Proceeds from all orders of Amatriciana will be donated to Italian relief efforts, so you can eat for a good cause:
Also, Riva Cucina in Berkeley.
Another way to help by eating out locally:
"The best Italian restaurants in SF join forces to help the victims of the earthquake in the town of Amatrice. One of the fundraiser events is being organized by Montesacro Pinseria Enoteca in collaboration with Pizzeria Delfina, Campari America, Acquerello, and many more. Delicious Italian food and wines will be served.
Save the date: Sunday, September 25. There will be 4 time slots between 12 p.m. and 8 p.m."
