Just a note on a lunch place I found yesterday -- I see from doing a search that it has been discussed here before, but not for a while. Yagura is a Japanese lunch counter on 41st Street and Madison, right across the street from my new office. Lunches range from around $4.50 to $5.75. Yesterday I had Chicken Udon, very tasty and with plenty of meat in it. I'm going back today.
Also there is a bakery on the same block which appears to be under the same ownership, called Cafe Zaiya.
