Greeks have been major players in Anchorage since the pipeline days.  The best pizza I have ever eaten was in a Greek pizza place just up the street from the PJ's Strip Club.  Learned the meaning of "Greek Style" pizza without sauce.  Later heard the Greek owner moved to Naknek and received rave reviews from the Seattle fishermen.  Closest to this gourmet delight is Pizza Olympia, also, on spenard Road.  Greek cuisine is unique and delicious with each chef providing unique spins on the classic foods.  Never got to Bethel, but can imagine from my own experience with Greek food prepared by immigrants how good it was.
