Is just any ol’ vegan sandwich in Hamberg a hamburger? 

 Why tired of Germany? 

 I think everybody here is non-binary and I'm waiting to be arrested for my intrusive thoughts. 

 I think you are OK in Hamburg, Berlin would be worse. 

 "Fischbrötchen" (fish roll)... is what they usually have there. 

 Hamburg ... the home of minced beef, which latter became the hamburger of America. 

 Don't forget the jelly donuts when in Berlin :^)
