I've popped into Don Antonio's Mexican Foods a few times now, and it reminds me of a number of little family places I visited in San Luis Potosí and Monterrey México. It's a family run place with grandma cooking in the kitchen the daughters serving tables. It's different from Mexico Lindo, a smaller number of dishes, but everything I have tried has been wonderful. Don't get me wrong I love the food at Mexico Lindo and will go there every chance I get, but it is nice to have a choice for Mexican food.
If you have a hankering for some real Mexican food prepared with a grandma's loving hand, I highly recommend you give it a try.
PS... If you like your food to have some kick you need to let them know otherwise they will tame it down for the salt and pepper is spicy crowd.
