Octave, opened in March 2026, serves specialty coffee from Plural, using a La Marzocco machine for its espresso-based drinks. Located at 32 Rue Lemercier, the café offers a variety of beverages, including a flat white priced at €5.50, alongside coffee-based cold drinks and plant-based milk alternatives. The 17th arrondissement is emerging as a specialty-coffee hotspot, stretching from Batignolles to Plaine Monceau, making this café a fitting addition to the vibrant neighborhood. With options for sweet and savory food, as well as takeaway, Octave also welcomes dogs and provides seating for those wishing to linger.
