One of the Tri-Cities' favorite Mexican restaurants is closing after 22 years.

Nobody is sure why Chico's is closing, but they put this sign up in the door Saturday night.

It's one of my deepest regrets that I never had the chance to eat there. So many restaurants are closing in the Tri-Cities lately before I get the chance to try them. A lot of times, it's new businesses. But we've been seeing some favorites fade away, too.
