There are 4 El Tarasco's in the lower Central Valley in California, and we ate at two of them while there between Thanksgiving and Christmas. One translation is 'the bite' - and you can get more than a good bite here. Both of the T's we ate at were on main streets in these small valley towns where the downtown is still alive - Hanford was really buzzing on a weeknight.
My wife and I did not experience any discomfort or feel out of place as one reviewer did, and certainly not ignored or treated anything less than very well by the staff, who were efficient and personable. While my wife speaks Spanish, we did not feel the need here, and we are both anglos. Also in regards to another review, it is not chrome and steel, but both spots were clean, so I hope and believe their experience was unusual.
There is nothing bland about the homemade chips and salsa (including salsa verde) and the fish dishes were very good, including the bass relleno and the fish tacos. The dishes did not suffer from overwhelming globs of cheese and the flavors were distinct. The refried beans were still not as good as Mexico, but haven't found really good beans outside of Mexico. We did not even know it was a chain until looking for a good meal a few nights later in Visalia, and it did not suffer at all from the blahs found in many local chains as they grow. Round it off with a couple light sopapillas without a trace of grease.
