Our brick and mortar shop is located in the heart of the historic Downtown Rockford, Illinois just 1/2 block North of State Street. For reference, we are about 1 hour north of Chicago. Our shop is regularly kept by owners Andy and Rikki Eclov and a small, knowledgable staff (say hi to Bobby, Andrew, or Ben). 

We're surrounded by wonderful local businesses and events and encourage a visit to Rockford if you've never been!
