Don Quijote is a discount department store/supermarket of sorts in Tokyo. The further claim to fame is that a few of them open 24 hours. I still haven’t visited it myself. Outside it is a busy crossing that connects Shinjuku Station and the famed red light district.
This was a ramen shop close to our hotel. We would go past it at various times and see lots of commuters and locals eating there. So we gave it a go on a slow and quiet Sunday. There’s the occasional travellers like us because it is close to the APA hotel in Shinjuku.
