Kirk here, introducing a fairly new Nepalese restaurant. I say “Nepalese” because the two gentlemen that are running it are from Nepal. But, I’m not sure how much of their menu should be classified as Nepalese and how much is Indian. The name of the restaurant is “Indian Curry Suizenji” (インドカレーすいぜんじ) and it is located near Suizenji Station. You can find a map and several 5-star reviews on it by Googling インドカレーすいぜんじ.
The menu is not vegetarian but they have some vegetarian items. I particularly enjoyed the freshly made nan. I was quite hungry at the time and would have enjoyed larger portions but I think you can get seconds on some items or perhaps larger portions could be negotiated.
I was told that they have another restaurant in Fukuoka but that they just started this one in October.
The last picture I’m uploading shows so items that they sell there.
