North Idaho is a little "north of the boarder" but they still have some muy bueno Mexican food. This is La Cabana, one of my son's favorite, located in Post Falls. They were even open later than we expected on a Sunday evening.
La Cabana is located at 604 E. Saltice Way in Post Falls, Idaho.... just over "the border...."
(....the Washington "border," that is, though you could pretend you were taking a little trip to Mexico if you'd like!)
There are some great choices for dessert, including deep fried ice cream and one of our favorites, flan!
