When I went to San Francisco I had one mission, to find a great Udon soup. I found it here. I saw this place through the window and saw only Japanese customers sitting inside, I thought that was a good sign. Being the only nos Japanese customer when i sat down gave me great confidence in the food available. The service was friendly and professional, extremely efficient. The Nabe Yaki Udon was almost decadent in its richness. Egg, chicken, mushroom, tempura shrimp and lots of udon noodles and vegetables, cooked to perfection. Umami, tasty, delicious and very good value. Breaking the egg yolk and letting it pour on the other ingredients covering them in richness and flavor was a highlight. The bowl is a very large serving, enough to share, but I still had to try the sushi so I ordered a single hamachi sushi to try the quality of the yellowfin tuna. I did not disappoint, I was in fact disappointed I was unable to order more. Reason enough to live or work nearby. I will return.
