You simply MUST eat at the Mission Inn in their outdoor courtyard if the weather is good. It's a quaint, perfect little spot for business, family or even a couples dinner or lunch. We were dressed casual (jeans) and it wasn't a problem. The menu was vast and the wine selection was fantastic. With appetizers, entrees, deserts and wine we were shocked at how reasonable our total bill was.
I highly recommend the Mission Inn for anyone in the area. Also stop at all the little signs around the property and learn about its history and heritage... incredibly interesting and beautiful.
