My family and I eat here often and we like this place. My favorite is fajitas and El Olmeca has a wider variety than most other Mexican place I have been too. In addition to the regular chicken, steak and/or shrimp fajitas they have a few others with different ingredients and spices. I like the Fajita Durango and the Fajita Jalisco. There are a couple of others that sound good but I haven't tried yet.
While this is not a high priced or fancy restaurant, it serves good food and the prices are reasonable, especially the lunch specials.
