One of the finest little towns in Central CA is Paso Robles. We've been there many times, stay at the Courtyard and explore the many wineries durig the day and dine at fine restaurants in the evenings. Weather is fine most of the year since Paso Robles is inland far enough to avoid the heavy fog layer that cometimes envelops the coast, but no so far away that there isn't a hint of coolness in the evening air.
Level 4 is an excellent place for beverages and food. Eberle and Tobin James make excellent wines and have great tasting rooms.
In all, going to Paso Robles (approximately halfway between San Francisco and LA on US 101 is a must-do.
