Where are the most common places where you can sit and read manga in Japan?

Question:

An example would be a ramen shop where you can eat and read manga at the same time. If anyone could tell me where in Japan and maybe the stores' name, that'd be great! Also, maybe a manga library would be good too. :)

Answer:

You can read manga wherever you like. Ramen shop? It's not a place to read manga. Or it's not a typical place.
