Hunter Ranch in Paso Robles is a great track, the back 9 (I think it is actually the front now) is about 3 strokes harder than the front.
If you don't mind driving a little bit, go play Monarch Dunes. They have a great 18 hole course as well as a 12 hole par 3 course that can be brutal in the afternoon with the wind coming off the ocean. And if you play there you are not far away from Jocko's Steakhouse in Nipomo. Famous for their giant steaks, but it's a crappy looking place (basic and old). The normal filet mignon comes in at between 16-17 oz and the extra cut brings it to around 24 oz.
