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 foods restaurant around - 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 theirqueso- 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.
