one of our favorites!. we've been going to abuelo's since moving to the dfw area and we've never been disappointed. abuelo's is one of the more progressive mexican foodsrestaurantaround - meaning they don't just serve the traditional mexican foods, they offer a variety of non-traditional choices.
as far as chips and salsa, their chips are thin and crisp. their house salsa is the roasted, smoky variety. i recommend their queso - it is bowl-scraping good! admittedly i am a spice wimp and if you want spicy queso, you will not be happy with this one - it is made with sweet peppers not spicy.
overall, it is a good value for good food. service has never disappointed, in fact on the most recent visit my server championed for me on getting a correction on my meal - nothing major just an oversight that she noticed.
