Can anyone help me identify where I took this picture in about 2011?

Hello!

I am 31 years old, and went to Germany for a month with my family during the summer when I was 16, back in 2011 (my mother was born in Bitburg and this is the only time she's been back to Germany since she was an infant; we live in the United States). We went to a lot of museums and historical sites as a family, as well as many parks and nature sites. We mostly stayed in small towns, specifically I remember us staying in Klosterreichenbach for a time, but we traveled kind of all over. I had a digital camera with me and took a lot of pictures.

My memory isn't great lately, but I've been able to track down the locations in most of the photos I've taken based on vague description and lots of searching. This one eludes me though! I believe it may have been taken in a cafe at some sort of museum? Not sure what type though. I'd love to remember though so that I could look into the history of the space. I think it's beautiful.

Thank you very much!
