Finally got around to trying out Chinchikurin last weekend. I liked it! I was actually surprised to read back through this thread and see that others had had notsogood timez at the Chin.
Granted, my okonmiyaki journey is in its infancy (and, as I have previously confessed, I have never been to Japan). Can’t say if I like Doya or Chinchikurin more - as @Starchtrade mentioned, the styles are quite different as this Hiroshima-yaki style was more noodle dish than the Osaka-style ufo pancake I had at Doya Doya. I liked both and would happily eat at either again.
