Onyx Tonics Specialty Coffee
Burlington · Downtown, United States
Why it’s on the route
Onyx Tonics is a downtown Burlington coffee bar run by Jason and Tiffany Gonzalez; Jason trained in the UK under Maxwell Colonna-Dashwood. It does not roast but offers a weekly rotating menu of six or more light-roasted single origins from local and US roasters, built around side-by-side tasting, and it is also known for its affogato.
