In a Napa house owned by two restaurateurs, the outdoor kitchen resembles the indoor one—minus a wall.

For John Hurley and Justin Hafen, who own Garibaldis and Sydney's Home Restaurant in San Francisco, entertaining guests is both a profession and a hobby. For their house in St. Helena, California, they asked the design firm Fisher Weisman to create an outdoor kitchen, dining room and living room for poolside parties. A beamed overhang supported by columns partially protects the space from the elements. The designers chose weatherproof materials: concrete floors stained Mesa Beige (from Scofield; 800-800-9900) and a dining table and chairs made of oiled teak (from the Bay Collection by Michael Taylor Designs, to the trade only; 415-558-9940). The upholstery is a walnut-brown weatherproof canvas by Sunbrella ($14 a yard from Outdoor Fabrics; 800-640-3539).
