Fun things to do in Santa Clara?

I’m traveling to Santa Clara for a week on business at the beginning of September, but should have most of my evenings free. I’ve been to San Francisco, and think it’s one of the best cities in the US, but I’m guessing traffic will suck too much to make it there in a reasonable time from where I’m staying (or will it?). Anyways, if anyone has some cool recommendations for good restaurants and places to check out I’d love to hear them.
