IL Cortile Ristorante, Paso Robles. This is a wonderful restaurant in Paso--everything prepared with skill and local deliciousness. Many of the veggies come from the restaurant's own garden. Highly recommended. Reservations a must.
Vindemia Winery - reviews say "This is my favorite winery in Temecula. I love it. It's like a secret little hideaway with the most beautiful view and relaxing atmosphere. I make it a point to stop and hear every time I'm in Temecula. It's out of the way from the other tasting rooms but worth the extra stop."
Vintages dating back to the beginning of Eberle Winery in the early 80's can be found [and sometimes available to taste] in the caves. The natural humidity and temperature makes it an incredible wine cellar! — at Eberle Winery.
