Probably the best authentic Mexican restaurant in the Pittsburgh area. We love their connected grocery store- fresh hot tortillas, salsa, chorizo dip. Their restaurant was also good. Not the best Mexican food I've ever had in my life (I'm born and raised in Texas, so a little biased), but the best I've had on the Pittsburgh/Pennsylvania area.
I'd recommend spending the afternoon shopping and exploring the strip and finishing with a nice dinner at Reynas. Also, true to most TexMex restaurants, their portions are huge.
