Taco Mesa's Brea location closed a while ago. It was replaced by Durango Grill.
On Tuesday's, Taco Mesa served a selection of soups for $1 each ... and $1 tacos, too. Durango Grill has continued this deal.
I like their soups, and the tacos aren't bad. On the regular menu, the Chile Colorado and Chile Verde are the only items I've tasted ... they're good, not great.
I'd recommend going early, as some of the soups sell out. They offer anywhere from two to four kinds of soup.
Durango Grill on Imperial, just west of the Brea Mall ... across the street from a McDonald's.
