Our Story

Rooted in Barrington,
crafted for you

Cornerstone Coffee Co is owned and operated by Rebekah Kallas — a woman-owned cart with deep roots here in Barrington. We set out to build something simple and honest: a heartfelt cup of coffee, made from the best our community has to offer.

That means partnering with Tala, our locally sourced and roasted roaster, and pouring every ounce of care into our in-house syrups. The result is coffee with character — and a place where everyone is welcome to linger.

Locally Roasted Beans

Every drink is brewed from beans sourced and roasted by Tala — our neighbors in the region — for a cup that tastes like the place it came from.

House-Made Syrups

We craft our own syrups in-house from fresh, local ingredients — no corn syrup, no shortcuts. Just honest flavor, made from scratch.

A Corner to Slowing Down
