The tacos are very good, the chorizo and carnitas are two of my favorite. They use corn tortillas for most of the tacos.
The biggest issue is that they have one flattop and do not clean it between items. Meaning if someone has a flour tortilla item before you it gets heated up and then the corn tortillas go on after it. my wife has had issues in the past where she has gotten a mild case of cross contamination.
The food is good but there is a risk, you can probably mitigate that by politely asking them to clean the grill before your stuff goes on but they do get busy often so you might end up waiting if you do.
