Thank you for the recommendation.
Went to Yum Ballam and , as you suggested had an assortment of fish appetizers (ceviche, shrimp) and the red fish Veracruz style.
I found it all interesting but had the feeling that this restaurant is going through a transition.
The wine list was interesting and reasonably priced.
Next time in El Paso, I will try the Cafe Central.
Your help was appreciated-YB was a better choice than what appear to be a number of TexMex type places.
