"Vermouth, Potato Chips, and People Watching A midday vermouth is a Spanish weekend ritual, and Bar Txurrut’s picturesque terrace is the best spot for enjoying one. Smack in the middle of the Old Town, Txurrut sits in the fabled Plaza of the Constitution, one of the world's best places to watch the world go by. Grab a seat and order a vermouth, but make sure to order it 'preparado'. This will get you a martini glass of chilled artisan vermouth, doctored with a touch of bitters and a dash of Amaro, shaken and strained. A bag of potato chips, open and sitting in the middle of the table, and the scene is complete."
