Your list is great. I'm proud to say that I've been lucky enough to try the ramen at most of your top 10 listed spots. I did notice however that you don't have Hatcho (Santa Clara) listed. They only serve ramen at lunch time, but it is both delicious and quite cheap. If you get the chance to stop by, I highly recommend it! Also, their stewed pork is quite tasty, more sweet and savory when done well.
