All in all, pretty good. The menu is fairly broad, and they have both north and south indian food. They offer five daily curry choices, with a mix of vegan and vegetarian. The prices are reasonable and the food itself is generally delicious.
The staff is fairly friendly from my experience, and as might be expected, English is no problem...the menus are in English and the staff can generally speak it. The one exception is the daily curry list on the blackboard, which seems to be Japanese-only, but that info is easy to get directly from the staff (including what is vegan or vegetarian).
The atmosphere isn't great, but there's nothing really wrong with it...just the usual basic type one encounters in most small Indian restaurants in Japan. It's certainly better than the nearby Veg Herb Saga, whose awful atmosphere I could never really get over. On that note, since they're both within just a few blocks from each other, the common question arises as to which one is better. Well, Vege Herb Saga seems to have a certain level of hype (especially for Indian natives, seemingly), but I prefer Veg Kitchen without question. My impression is that Vege Herb Saga started off strong because it was not really meant as a true "restaurant", but rather as a place for the owner and other nearby Jains to eat...serving the public seems like it was more of an afterthought. But for the same reason, after a couple of years, it seems to be struggling and has deteriorated. Veg Kitchen on the other hand seems more of a pure restaurant, run by folks who understand the restaurant business itself much better. That may make it more "average" perhaps but I just find it a more consistent and pleasant experience to eat here. And anyway, the food here is just as good if not better, as far as I'm concerned.
A decent choice for vegan curry.
Cons: So-so atmosphere
