They boil their noodles in the same water with the other noodles, so you need to call ahead unless you don't mind waiting a long time. Also, it appears that the chicken soup with buckwheat noodles is the only thing I can eat. The food tasted ok. It was just some noodles with a couple of pieces of chicken and lots of raw onions for $15 excluding tip and I'm still hungry. I think that is pricy for lunch, given what it is. I don't recommend this place.
They have 100% buckwheat soba here. Score!
