Definitely the best coffee in the area in terms of quality, flavor, and the use of natural ingredients. Service is also stellar, something I normally don’t experience especially in Stockton. Lastly, it’s a great place to hang around or study with its nice aesthetic!
It's our first time here. Me and my mom liked our orders (Thornton Thorn and Diablo Mountain). I was amazed with their coffee flavors it's unique and flavorful... I'll bring my daughter and husband here next time...😊...will try their other coffee flavors...also the staffs are nice too!
I enjoyed the Thornton's Thorn coffee with oat milk. The shop smells so good, but was still tolerable for my non-coffee liking father. It is very clean and there are games and a free library to check out. I look forward to trying one of their sandwiches one day.
My wife and I tried this place out! She got a peach tea and I got "Ben's Fave" with a panini and a chocolate croissant. Absolutely great service, very mellow lowkey environment. Definitely will stop by again.
You can definitely taste rhe coffee here no joke. Love how it actually wakes you up. They use nothing but natural flavors. This place is a win win. I got the Rosa coffee with honey for sugar and added lavender 💜 My mom got the chi tea 🍵

Bold, natural coffee that truly wakes you up—crafted with pure flavors in a cozy Stockton spot.
