    The owner and Baristas, Pedro/Peter. Is a very nice guy, once he gets to know you. Makes an excellent coffee. If you go there regularly, he will know what you will order without asking. Definitely a local personal type of place that makes you feel like home.

    Cup O' Jo was easy to spot. biz looks likes 2 parts, right is service area, left is seating.

    inquired upon entry: can i use their restroom first? stated i would buy a coffee afterwards.

    was told "no" i had to go down to "the park". tone sounded very annoyed. off i went to find the park. upon returning, i passed this Jo. it's nearby a deli that's been in the news recently...for a tweet about a free side...

    First time trying and honestly have lived in Clayton most of my life! I'm in shock I've never been here before. Met my wedding photographer here with my mother in law, who is super picky about chai lattes. She Ordered and LOVED It!! Super hard to find chai with good flavor, it was so delicious I could smell the aroma!!!! Ordered iced coffee and it was also really good! I was nervous because of the comments about the rude staff, however the guy was very kind and answered all our questions. He might not be a bigger talker /face contact but I think people are judging a bit too hard, not everyone is an extrovert! And that's ok. So good I'd come back again!

    The play room is gone :( which was the only draw for me having a child. The lattes are never good, so I had to stop coming for coffee. Maybe a hot cocoa for my son. I want so badly to like the spot but the service is never friendly from the owner and now that it's not kid friendly I won't be back. I wish it were different. Clayton really needs a great coffee spot.

    Nice small town coffee shop. Seating outside, friendly staff. Decent menu. Fair prices.
