Time Out says
Coffee Jar opened in 2013 when owner Maria quit her finance job to focus on baking over banking, and Camdenites have been embracing the place enthusiastically ever since. There’s seating for just ten people, with minimal decor that makes use of large quantities of reclaimed scaffolding board. The house beans come from Monmouth, with a changing roster of guest. Our espresso came from the hand of a barista who worked meticulously, right down to warming the cup with a puff of steam to ensure a properly hot shot. The food offering is sharply focused: a few sandwiches, plus baked goods both bought in and produced on-site. Add on friendly service and you’ve got a winning formula. We can see why most of the customers during our visit were loyal regulars.
