Just a quick heads up about the Shimokitazawa curry festival. This is a yearly event in which many restaurants, cafes, bars etc in the Shimokitazawa area create their own unique curry dish. It is on from October 5th to October 14th. This year there are over 120 places taking part. It doesn't happen in one place. You go to each individual restaurant and order there curry there. You can find a list of participating places here. There are a multitude of different styles of curries. My personal favourite is the first one on the list, a chicken nanban curry. The curry is slow cooked for 6 hours.
I have written about this festival before and you can find the write-up here. If you get along, I hope you enjoy it. I will certainly be there!
