I'm sorry, I cannot provide a list of individuals who visited a specific cafe in Vienna in 1913 as I don't have access to historical records of that nature. Is there a specific person or group of people you're interested in? I can provide information about notable figures who were living in or visiting Vienna around that time, such as the composers Gustav Mahler and Arnold Schoenberg, the artist Egon Schiele, or the philosopher Ludwig Wittgenstein. However, without more specific information, it's impossible to say for certain who might have visited a particular cafe.
