I hesitated a lot before including Capricciosa in my list. It certainly isn't an Italian restaurant, the food there is a Japanese invention and it really isn't very good. On the other hand, ubiquitous, cheap and popular as it is, a list of its phone numbers might be a service to my readers. So I bit the bullet, and here it is. Business hours differ, but in the main go from 11:00 to 22:00. Menu in Japanese and English.
