It is an Indian restaurant that has a shop around Ginza Kyobashi.
This is rather a South India dish, and the photo is a set of Meals.
Indica rice (free to change) is on top of large banana leaves.
You can mix this and various kinds of curry as you like.
It's not very familiar to Japanese people, but it's delicious even if you eat it by hand like authentic India.
It seems that a good way to eat is to use only the second joint of the finger.
If you are not used to it, why don't you ask the clerk how to eat it?
