Hildale UT is the home of the Fundamentalist Church of Jesus Christ of Latter Day Saints (FLDS), a polygamist breakaway sect from LDS. The cafe has articles about the area’s history of polygamy on the walls, so it’s hardly a big secret. It is run by polygamist wives. This is where their leader Warren Jeffs was from, before he went to prison for accomplice to rape for officiating a marriage between a 14 yo girl and her 19 yo cousin.
The food was excellent and, as appears to be the norm in Utah, the people friendly.
The Mormon Church (LDS) takes great pains to point out that FLDS is a breakaway sect, that LDS no longer practices polygamy, and that FLDS members are not Mormons – statements which are completely correct.
