Picante is not especially cheap for a Mexican restaurant, but for its flavors, freshness, and association with Chez Panisse, it's a bargain. Their food is extremely delicious, the setting is beautiful (with a lovely patio), and they have great extras on the menu such as Mexican wedding cookies, chocolate angel food cake, several high-quality aguas frescas, and Mexican hot chocolate at weekend brunch or breakfast--plus it is one of the few Mexican places in the area to serve breakfast at all. They make all of their own tortillas right there in the restaurant, and the results are incredible.

There are some nods to California cuisine, but on the whole it's pretty authentic. Although the noise level is a bit high and it's pretty casual, it's a good place to take a date, especially if you explain the whole Chez Panisse connection. They have a website with sample menus at http://picantecocina.citysearch.com/
