I once wrote about uniquely themed restaurants in Tokyo in this post. These restaurants are a kind of entertainment, so people will probably soon tire of them and the restaurants will have to change gears quickly. Diamond Dining Corp has a lot of entertainment restaurants, I checked out their site after a long time. I realized that they have some "Alice in Wonderland" themed places. Maybe Alice will be a popular theme. Here is one in Shinjuku and this is another shop in Shinjuku too.

Honor system shops are easy to find in Japan. Here is a collection of photos of such shops, usually they sell fruits or wild vegetables they find in the woods like takenoko (bamboo shoots). There are some around my home and sometimes I buy vegetables from them.
