I went to Halibut Box (or Halibut Jack's, or Halibut Haven, not sure of the name) in Valdez, Alaska and had the rockfish sandwich without fries. It was fresh, covered in shredded iceberg, pickles, and American cheese--a list of chiche. It had an old school vibe. Rockfish, also called black bass, or sometimes miscalled "sea bass", are caught all over Alaska in the salt water. They are aggressive and often feed in schools. I loved my sandwich, and especially the little placemat that came on the tray and showed a map of the coast with different fishes chasing a school of baitfish.Now that I think about it, the place was called "Halibut House", and it's worth a stop.
