My boyfriend and I stopped in for lunch yesterday. We were hoping to sit outside, but there was a bit of a wait so we headed downstairs to the inside seating. The restaurant has a really authentic feel and if I remember correctly, some nights they even have live music!
We started off with chips and salsa (the house salsa and tomatillo verde). For $3, they gave a huge pile of freshly made chips! The salsas were very fresh tasting, although I think they could have been a bit spicier. We also got a margarita shaker to share - it wasn't particularly strong (that's how I prefer it) but I could see other people wanting them stronger.
We each got tacos for our entrees. They came with rice and refried beans as well as some spicy cream sauce. I had the fish and the al pastor tacos. The fish was cooked nicely but could have been a bit more flavorful, and the al pastor was a little too salty but I still enjoyed it. Service was quick and friendly as well.
Overall, I think Casa Reyna is a great value for all the food you get and is one of the better authentic Mexican restaurants in Pittsburgh!
