Quince is San Francisco elegance rooted in the Italian-Californian relationship between farm and table. Michael Tusk's cooking draws on pasta, vegetables, seafood, olive oil, herbs and the restaurant's farm connections, but the result is far more polished than rustic. The Jackson Square dining room sets a formal tone, while the food keeps returning to freshness and season. It is a restaurant where luxury is made to feel cultivated, not merely purchased, with California produce carrying much of the glamour.
