There's a lounge on the 2nd floor of Elim Kasuga-chō, a building directly connected to Nerima-kasuga-chō Station.
The lounge is located in front of the entrance to the Kasuga-chō Library, and it has tables and sofa benches.
I forgot whether eating and drinking is allowed. If you've visited, please leave a comment!
More than that, depending on how you look at it, the backrests are shaped like Hato Sablé cookies, which was cute.
So, why not try using this spot as a relaxing break area around Nerima-kasuga-chō Station?
