Thanks for all the suggestions!
It ended up being a kid-focused weekend. We brought Alec and a friend. With Alec, we can usually con him in to good restaurants, but the friend is the mac-and-cheese only variety.
1st Day - Winchester Mystery House and dinner at Bella Saratoga (fine but not wonderful) in Saratoga. We stayed at the Moorpark (nothing special) in San Jose.
2nd Day - NASA Ames Research Center then on to Santa Cruz and the Mystery Spot. Unfortunately

we didn't have time to hit the Bigfoot Museum in Felton. Stayed the night at the Coast Hotel in Santa Cruz (great location for a Santa Cruz vacation with kids, nice views too). I couldn't get enough votes to drive to a good restaurant so we ate at Riva on the Santa Cruz pier. Again, OK, but nothing special. The next morning I spent on the verge of nausea with one ride after another on the Boardwalk. (How do these kids do it

?!)
All in all, a nice trip. It's fun to take mini vacations in your own "backyard" and although our destinations were kitschy, that can be fun too.
