What do you mean? I'm simply curious since from what I know udon is basically combining water, salt and flour. While you can't do much about the salt but it shouldn't be too bad as long as you dont put into much. While the water and flour ratio can be modified as you massage the dough. And even if they mess up the resting portion of the dough ot should result in an okay noodle, probably not as good as one rested properly though.
As for the stock, you are basically getting the flavor of the base into the soup which is why you can make the stock by boiling water with the bones or vegetables by boiling it for a sufficient number of hours.
Besides even if the flavor isn't that good. I still think it would be miles ahead from the crap they are having
