Boris - Rue Caulaincourt has been part of Montmartre's vibrant coffee scene since September 2013. They serve espresso-based drinks made with beans from local roaster Lomi, and offer a selection of sweet and savory food options. Open seven days a week, the café provides seating for those looking to relax, along with takeaway drinks for those on the move. The eclectic character of the 18th arrondissement enriches the experience, making it a stop worth visiting beyond the usual tourist routes.
