Alaire

From the Condes de Barcelona hotel lobby, a sparkling glass lift zips up to this sleek 8th-floor roof-terrace bar with soul-stirring views across Passeig de Gràcia and La Pedrera. Sunsets are exquisite, particularly over a cava (€8) or Penedès wine (€7). It gets packed with a stylish young crowd of locals and visitors; you can book only if dining (mains €10 to €16).
