Just like food stalls in Tokyo this little "restaurant" has, despite being really small, his own flair.
Against common believe that japanese people eat mostly just sushi, Kuishimbo serves traditional home-cooking. That means a lot of different Ramen or Udon Soups, Okonomiyaki or Rice bowl Dishes (Donburi) are to choose from. With a lot of different side dishes like Natto-pancake or Ebi Fry.
The food is delicious and also well known to in Vienna living japanese people.
The only small flaw is that the food, especailly because it is mainly home cooking stuff (so acutally nothing really special) is a bit expensive. So not something for everyday.
Also if I mean little I mean super small. There is just place for maybe 6 people in the shop. In summer you can sit outside but I guess the direct view on the quite busy Wienzeile street is not everyones cuppa.
Still good for an interesting lunch.
