I used to go to Sazón (1816 South Lamar) with relative frequency, as it's not too far from my house and I've always enjoyed their interior Mexican cuisine. But it had been about 2 years (or more?) since I had been -- shame on me! Their on site parking got a little tougher in recent times, and apparently that has stymied me from dining there along with the onslaught of traffic on South Lamar. But Sazón is still standing in the face of over-development along this corridor.
I ordered the Ensalada Mexicana, which clearly was made fresh. The spinach looked like it just came out of the bag, and had almonds, tortilla strips, ancho chile, and a nice vinaigrette that I remember liking, but now I can't remember what the flavor profile was.
In the past, I have been very pleased with their mole negra de Oaxaca and the cochinita pibil, both traditional interior Mexican dishes. Sazón is also one of the few places I know locally that serves huitlacoche (corn smut... yes, smut -- look it up!), which they put in empanadas. They do have enchiladas, but these are not your greasy Tex-Mex type.
So if you're looking for good interior food, and can grab a parking spot, stop by for breakfast, lunch or dinner! I've actually never been there for breakfast, so I'll have to check that out. I also remember their margarita at happy hour being decent. I've linked to their Facebook page, but normally they have a website at www.sazonaustin.com which shows their menu, but the page is currently not functioning. Their Yelp page does have a link to their menu though. Sazón has nice atmosphere, including a outdoor patio on the Lamar side; the food is not fussy or trendy, just good and fresh as it should be.
