Here's a bar called Sushicafé Avenida that's designed by Saraiva + Associados (Associates) in Lisbon, Portugal. I can't help but notice those interesting stairs. I wouldn't want to use them after having cocktails, lol!
Years ago I had a dream about a downstairs office from the master via a spiral staircase. Don't love the execution, but happily remember my dream as a result of this image. Flashback: Casa Do / Cazú Zegers
