This narrow alleyway is famous for its tiny bars and eateries serving up Japanese street food. (sadly nothing vegan or vegetarian here)
It has become a popular tourist destination, so I recommend to head here early if you are planning on taking pictures! It usually starts to get really crowded from 5-6pm when many Japanese return from work and go here for a quick bite.
Please be aware that this spot is so tiny and people are working here to prepare for the evening so do not attempt to put a tripod here as there is no space for it and it's also not allowed.
