In Tokyo, if you have a two story house in a residential neighborhood, *by right* you can put a restaurant/bar/boutique/workshop inside the ground floor of your house! Gives the backstreets a totally different feel to walking through a US neighborhood with nothing but residences.
Today on my morning walk to get fresh bread for breakfast, I passed a very tiny home bakery near my house. I love these tiny businesses in the suburbs that people run from their living rooms! I’ll be coming again. (The lemon pie is divine!)
