One nugget from Zagat’s 2012 survey of Bay Area restaurants that has gotten less media attention than The City’s below-average tipping is San Franciscans’ mixed feelings about food trucks and carts.

The mobile meals are ranked both in the top three and worst three developments to San Francisco’s food scene in Zagat’s 2012 survey, which is based on responses from more than 10,600 Bay Area diners.

Online reservations took top honors as the development diners liked best, followed by food trucks. Survey participants ranked the local-sustainable movement as the third best development.

Joining food trucks as the worst developments were noisy restaurants and small plates and portions.
