Thank you Yelpers for your help in finding this great place! Great, authentic Mexican food that was served with a smile and very quickly. We had the good fortune of sitting by the owner (or one of the owners). What a great guy! My son and I felt very welcome and we were invited back to celebrate Cinco de Mayo. We live an hour away and really wished they had a location close to us (Anthem - hint, hint).
Do not pass up the flour tortilla chips! They come out warm and are addicting. I had the carnitas plate which was very good (and spicy!) and my son really enjoyed his taco burro.
Will definitely visit Espo's again when we are back in the area.
