The wife and I were just there a month ago. We stopped at The French Press on State St. I had a latte and she had a Matcha latte. Both were very good. I also was told Handlebar was an excellent place but didn't get to try that one.
If the wife likes orchids go to Santa Barbara Orchid Estates. One of the best orchid nurseries in the world. Only 10 minutes from the French Press.
Enjoy your time in SB.
