I grew up in SoCal eating Mexican food at hundreds of Mexican Restaurants and with Mexican friend's families, as well as from taco stands in Mexico.
These tacos are every bit as good as ANY I have ever eaten...maybe better.
Also, in the butcher shop in the store, you can buy prepared meat for tacos etc.
But don't take my word for it, ask the Mexicans waiting in line for the tacos.
There are NO OTHER tacos in Pittsburgh.
