The key here is to go in when they open their ovens baking some of their excellent pastries. I never leave without getting a freshly baked crossiant or churro. My wife introduced me to La tolteca and we have been making regular trips back ever since. We started out with breakfast burritos on weekend mornings and I have now fit it into my drive home from golfing for some tacos. Both of the aforementioned are excellent.
It is really hard to find authentic homemade Mexican food and this place does it perfectly. I was convinced when I had my Mother-in-law's homemade rice and tacos that it was the best their was. I am not saying that Tolteca is better but it actually tastes close to the same.
A little hint: Once it cools down a little bit, fall and winter months, they have a huge charcoal grill setup in the parking lot on weekends. You can get cooked whole chickens and full racks of ribs for around 8 bucks. They also cook fresh green chiles. A great alternative on game days when you don't have time to setup the grill before the game starts. Just run down and pick something up fresh off their grill!
