My top recommendations:
1. Cinnabar Hills- 27 Holes (San Jose)
2. Roddy Ranch (Antioch)
3. Wente (Livermore)
4. Callippe Preserve (Pleasanton)
They're all relatively new courses, but they each display character, memorable holes, and good conditioning.
*They all have decent websites for checking out the pricing, previewing the course, ect.
