Update 2009 - Cool has moved - best as I can figure they now how two places on Hildalgo - one by the town square and one further down.

Excellent homemade gelato.  Above, my favorite so far, Kaluha.  Upper right is coconut and below that a high impact chocolate.  Had a taste of the nutella -  also very good.

Neat dipper people and, next to the counter some beautiful homemade jewelry.
