This is an old school Mexican restaurant that was founded over 65 years ago and was originally located in downtown Mesa, AZ off of Main Street in between Stapley and Mesa Drive. I was in utero when I had my first taste of this place, as my mother craved it while pregnant (every time). I would always want to eat here for my birthday growing up. Although the restaurant has moved and the family has a few break off restaurants, its hot sauce and chips remain my favorite on the planet. I also enjoy Gloria's chicken fajitas and their special sour cream that's spiked with some addictive drug (I think). This place is a true original in Arizona. For all of you diehard Mexican food lovers,this place deserves a try, on its legacy alone. I really enjoy their beans,rice and their green chili is delicious as well. I will say it once again, their hot sauce (runny hotter variety, not chunky) is my favorite hot sauce on the planet. I'm ridiculous when it comes to this stuff. I will actually buy a liter of it(Love the metric system we should switch) and use it on any and all Mexican food and several other items I eat. The drive to Mattas is about forty minutes from where I live, but for me, it's worth it.
