That's all, really. I had heard it was serviceable and wanted to prevent anyone else from encountering the very ordinary and not-delicious tacos, tortas, and ceviche which we had.
The ceviche was worse than Tonny's, which is not very good (but which is just 4 blocks away).
The torta was something I would not serve in a prison. No avocado (no option to get any either), dry yet greasy meat, limp lettuce, hamburger bun, Tapatio sauce in little plastic packets.
The tacos my wife had were carnitas and chicken. The chicken tasted like it had just come out of a can. The carnitas were the only item we ordered that tasted like food, and Tonny's carnitas or chili verde knocks the crap out of them by a long shot.
In a town with King Taco and Tonny's only minutes away (walkable if you please), I don't see the point of eating at La Estrella. It's not that much cheaper (in fact I think it may have been more expensive than King Taco) and is not in the same league for quality as either of the above.
We were quite disappointed and "ate there twice" last night (the first and the last time)!
Hope this saves someone else the trouble. Go to Tonny's or King Taco if you want Mexican in Pasadena. (Or if you want ceviche or fish tacos, Senor Fish in South Pas is as good as it gets.)
