This hands down my favorite taco place..ever! Not just in Pittsburgh but I like it more than any other taco place I've been to - and that's saying something because I grew up in Texas. The tacos taste pretty authentic based on what I have eaten before and even though the chicken and other meats are very simply cooked - it somehow holds so much flavor. My theory is that the chicken tastes so flavorful because it's cooked on the same surface as the beef and other meats so it essentially gets infused with the flavors of the onions, beef, pork etc as well.
Maybe my attachment to it has to do with eating it so often in college (once a week at least) but I think objectively, it's really flavorful too! It's also pretty cheap - $2.50 a taco and two comfortably fills me up and people significantly bigger than me usually buy 3-4 max so it's a pretty affordable lunch/dinner.
