I work on 51st between 5th and 6th ave and am looking for nearby locations where I can get take-out udon soup or something similar (not looking for chicken noodle soup, anything asian is ok). I actually like the korean soup at cafe duke on 51st between 6th and 7th, but they charge $8 + tax, which is a little high for lunch. Anything for under $6 nearby? I'll even go up to $7. Obviously I want it to be tasty, but it need not be the best in the city, just conveniently located and well priced.
