Between Williams and Kingman we stopped at the Seligman Sundries in Seligman which was a general store, mostly a gift and memorabilia store with lots of 1950's merchandise on display.  It was a trading post and soda fountain since 1904--Ted's Fountain & Trading Post until 2007 when it was renamed by the new owners.  We had a delicious hand made chocolate malt and stayed 45 minutes talking to the owners.
