I’m in Berlin since a few years now and one of the main thing I miss are places where I can go and read good comics, that’s not really something as developed here, majority of people I meet don’t even know that’s a thing.
As a contrast, in Switzerland or France I can go to any Fnac store and spend a Saturday afternoon reading comics from a huge set of artists.
If you’re in Berlin check out Dussmann if you haven’t already (it’s hard to miss …). It’s nowhere near as well stocked as an average book shop in France but it does probably have the largest collection of BDs of any shop in Berlin.
Speaking of broadening people conception of BDs, I highly recommend people to have a look at La Revue Dessinée, a quarterly news magazine in BD https://www.larevuedessinee.fr
I don't know, that's not the way I see it personally. I see roman graphiques as more experimental concerning the narration, art, even how the actual book is produced (experimenting with different type of paper, different format) where traditionnal bandes dessinées have more strict codes they follow. So yes it can feel a bit more serious in some way but you also find weird and funny things.

I read A Contract with God and some other of Eisner's stuff lately, e.g. The Plot: The Secret Story of the Protocols of the Elders of Zion, and the version of the "To be, or not to be" speech in Comics and Sequential Art - just awesome.
