The Mayo Family Reserve Room (there is also one in Healdsburg) is the food and wine pairing sister to the main Mayo Family Winery tasting room in Glen Ellen. At the Kenwood Reserve Room, it's all about food and wine pairing and Mayo does it very well. Approximately seven different wines are paired with small samples of food, expertly prepared by an in-house chef.
It's highly recommended to call ahead for reservations. Mayo accepts walk-ins but you run the chance of a long wait depending on the timing. Much better to call ahead and go tasting for an hour or so prior to your appointment. Groups of ten or more should definately make reservations as the tasting room is small.
