I have read the very small number of entries for Düsseldorf. I will be traveling to the city to meet up with a friend living there in August. I would like to arrive ready to see the culture and do not want to depend only on Köln [Cologne].
Therefore my question is, Are there some Through the Back Door places that I should pay attention to when visiting around Düsseldorf? I appreciate any assistance you might offer. Thank you in advance.
