Find La Superica in downtown SB. Julia Childs rated it one of the best resaurants in town and it's a taco shop w/fresh, homemade everything. Lazy Acres Market has a great selection of wine and food. Ask for Bob in the wine dept. if you have any questions. The Wine Cask also has a great selection but, imo, a little more expensive.
If you head further north, stop in SLO, there is a great Thai restaurant downtown (name escapes me but it's across the street from Woodstocks). Blue and Novo are also tasty.
Morrow Bay has a fantastic view from Windows on the Water (Morrow Bay Wine Cellar is just below and I've found some good prices on Turley) and pretty good food. The best restaurant I've found in the central coast is Hoppe's Garden Bistro in Cauycus. Great wine, great food and a nice setting. I'm sure you already know about the Sow's Ear in Cambria.
The Wine Outlet in Atascadero also has some good finds and some reasonable deals.
Have fun! When is that house going to be ready?!?
