A restaurant, bar and coffee shop on Helvetiaplatz
Bank is open daily from breakfast time til late. Located on Zurich's trendy Helvetiaplatz, this is a great spot for people watching whether you're here for a quiet coffee, a bite to eat or one of their signature cocktails. It's also an intimate venue for live music, readings and the regular "Tischgespräch" (table talk) discussions.
