What can I say, everything you have heard about Postino is true. It's top five of my favorite restaurants, and my go to choice for people visiting or new to the valley.
While they have sandwiches and soups, their bruschetta boards are where it's at! They have quite a few options (that can be made gluten free), but my favorites are the fig/prosciutto, apple/Brie, salmon/caper and the mozzarella/tomato.
On M/T, starting at 8, you can get a bruschetta board and a bottle of wine for $20.
