OK, I'll start with a disclaimer, I absolutely adore the people that run this restaurant and have been going to their restaurant since I moved to Phoenix around '91 (two locations ago).
However, I have taken countless people to try the food from my native country and EVERYONE has LOVED it. From my vegetarian to foodie (or chowhound) friends have found something (usually more) that keeps them coming back. Many thank me for having introduce them to this jewel of a restaurant.
My favorite is the Mojarra Frita becaus it brings back memories of growing up in beautiful El Salvador. I recommend the Especial Combinacion de Eliana's for first time visitors -- it has a Salvadorean tamale wrapped in banana leaf and is moist like a mousse; the tradtional pupusa and a savory turnover called Pasteles ($6). For a hearty meal, the I recommend the Bistec (beef) or Pollo (chicken) dishes that come with salad, rice, beans and Salvadorean tortillas ($8.95)..
After reading some of the reviews, I just liked to say, thank you for trying out this food but it is not Mexican food. I can recommend some of those if you msg me
