Nomad Coffee Lab is a specialty coffee cafe tucked inside a building in an alley just off central Barcelona, at Passatge Sert, 12 in Ciutat Vella. It serves espresso, cortado, and filter coffee from beans chosen among Colombia, Ethiopia, and Costa Rica, with no desserts. Most orders are takeaway and drunk standing, and a line forms around noon. Indoor seating is limited to a few bar-table spots and two or three seats by the window.
