This is the work of Japanese artist known on Flickr as Toti Kaida, here. Her website is here. Her work is so whimsical and funny. She is sort of a cross between Renilde DePeuters, here, and Sabine Timm, here.
How I would love to have one of these cafes in my neighborhood! It's that time of year when curling up somewhere cozy to drink a latte and watch people is just what I want to do.
