This. Place. Is. Awesome.
I've been here several times and it has never disappointed.
This place is as authentic Mexican as it gets in Pittsburgh. I'll admit I've only ever ordered a variety of their taco selections but that is because they are so incredibly delicious. I love the Filet Mango Tacos as well as the fish tacos. All their ingredients taste so fresh and love their combination of sauces and spices. Their salsa is not my favorite, but the queso and guac are quite tasty and flavorful. I believe another true sign of a great Mexican restaurant is if their rice and beans measure up - they do here. The authentic Mexican cheese on the beans...so yummy.
I do like the margaritas, but don't ever drink more than two! They are uber strong!
Bonus - family friendly. They have high chairs. :)
