LOVE their beef udon! It's the best udon I've ever had at a sushi restaurant. The broth is spot on- not too salty and not too plain. My bf and I have made it a tradition to stop in here for some udon and maki rolls whenever we visit Madison.
Ask the waitress to split the udon into 2 bowls for easy sharing. (Note: they charge $1 for splitting into 2...)
