It's hard to say what makes a great cafe--is it comfortable seating? Friendly service? Exquisitely brewed coffee? All of these things certainly help, and they're not so hard to find among the vineyards in California wine country. Pretty much anything that passes your lips in Napa Valley is carefully considered, and the coffee is no exception. It may not be locally grown or seasonal, but you can bet that it's fair trade, meticulously sourced or lovingly roasted, with water that's just the right temperature. In terms of atmosphere, the valley's cafes run the gamut from cozy, like at the Model Bakery, to bustling, like Ritual Coffee Roasters, to more restaurant-like at Boon Fly. The newcomers Molinari Caffe in Napa and Sogni di Dolci in St. Helena are the cool cats of the bunch, while the Yountville Coffee Caboose is a quirky, beloved local spot. They all have their niche--whether its a Ferrari-like espresso machine, pour over cones, or the more classic French press. Nearly all of these cafes offer sweet treats baked by pastry wizards in the area, and many of them have more substantial fare like sandwiches and salads. They are all good choices if you're looking for a breakfast at the start of your day, a place to stop in for a caffeine fix or cozy up during the afternoon, or a light bite when your energy starts to wane.
