Really nice cheap food within walk of Carnegie Mellon and Pitt campus!!
These street tacos are served at the front of the Mexican grocery store. All of the tacos are $2 (not dirt cheap but they give you a nice-sized taco and lots of fixings).
The guy is continually cooking the meat on the grill in front of you while he pumps out tacos and the meat is really fresh. Tacos are served in two corn tortillas, which he also grills right in front of you. I highly endorse the ribeye steak taco--- a slab of beef instead of more traditional chopped-up meat, with really great flavor. The chorizo taco is pretty good also.
Even better, you put on your own toppings-- fresh pico, avocado-tomatillo salsa, red hot salsa, cilantro, onions, etc...
I loved this place and would go here really often if I lived in this neighborhood.
