Chocolatería San Ginés is Madrid's oldest chocolate shop, famous for its delicious chocolate and churros combo. Established in 1894, this cozy cafe serves up steaming hot chocolate and crispy churros 24/7, making it a popular spot for both tourists and locals. The authentic Spanish vibe, with green chairs and old-fashioned decor, adds to the charm of this must-visit spot in the heart of Madrid. Tip: get the parros instead of the churros!
