Transform this narrow, high-ceiling space into a trendy coffee shop with a minimalist and modern design. Incorporate warm wooden elements like wooden paneling or accents on the walls and ceiling. Keep the hanging pendant lights but integrate modern lighting fixtures for a cozy atmosphere. Position the coffee bar at the opposite end of the room (au fond de la pièce) from the entrance, with a light-colored concrete countertop. Add sleek wooden tables and chairs along the walls, ensuring the seating feels minimalist and comfortable. Use open shelving for displaying coffee products behind the bar. The walls should not be glass but solid, allowing for wooden or minimalist design accents. Keep the overall style clean, modern, and welcoming, with natural light coming in through the front windows to create a bright and airy ambiance.
