Very long line - seems like this might be a bit of a tourist attraction. GOt the smallest portion size for 1000 yen. The mixed vegetables and seafood dish that comes as part of the set I did not get but I regretted it - everyone else did. Not sure what was so special about the noodles themselves as they didn't taste that different from regular somen or thin udon to me - but the duck based broth was outstanding - really rich without being too thick. I could have drank about a gallon of that. Get there at 11:20 when it opens to beat the line.
