RE: Places to eat in the Indio, California area
A very unique Roadfood treat can be found in California's Inland Empire: the date shake. This is the biggest date-growing area in the US; I've never seen a date shake anywhere else. Cool, rich and very refreshing; my favorite was always at a place called Hadley's, in Cabazon (about 40 miles from Indio).
Indio is home to Shield's Date Gardens. Many types of dates and other fresh, wholesome foods can be found there, too.
But a date shake is definitely a must.
