A perfect place to grab a coffee. Cozy, and nice environment. We stopped there for a cup of coffee in the middle of our bike ride to Morgan territory regional preserve. If you are in the Clayton area I highly recommend visiting for a cup of coffee.

It is a great place to grab a coffee. It is a small location, but there's also a small area for outside sitting.

Cup o Jo is like stepping back 40 years in time to Berkeley and the days of the boho coffee shops. It’s a wonderful, eclectic interior with signs and messages and art and music. All reflecting Peter‘s personality and taste. Excellent coffees and they also have juices and ice cream and pastries. take it from a guy who been frequenting coffee shops for espresso since the late 60s. You’ll love it. One caveat: no bathrooms, although there is a public bathroom in a park about two blocks away.
