"It’s got trendy cocktails, DJs, and a fashionable crowd, but the real reason to head to this swanky lounge is for the views—of the sea, the sky, and the whole of Barcelona below. Located 26 stories up, on the topmost floor of the renovated oceanfront W Hotel, the sleek bar is wrapped in floor-to-ceiling glass; there’s simply no better spot to watch dusk fall and the lights of Barcelona twinkle on than from a coveted window seat here. The cocktail menu changes seasonally, but mainstays include the watermelon martini and passion fruit martini; there’s also a rather good sushi menu. DJs start spinning at 11 p.m. on weekdays, midnight on weekends, and that’s when the party really gets started—after all, nothing happens in Barcelona before 10 p.m. Be sure to reserve a table in advance, and dress smartly."
