A welcome addition to the P'burg area! This place is the real deal when it comes to Peruvian food. I went there for dinner with a friend who has spent time in Peru, and this freind commented how delicious and authentic it was. In comparison to the other Peruvian places he has tried, Inca Peruvian was at the top of his list. I can't remember everything we tried, but the patatas "huracainas" were among the dishes we ordered. They were great. All of the platos we sampled were really flavorful. The menu is also quite extensive and the portions were huge. The prices are super reasonable as well.
Service seems to be an afterthought here though. We were the only table in the dining room (until other people arrived toward the end of our meal), and it took us a long time to get the server's attention to get anything, including the check, which took like 15 minutes to get. If the restaurant is busy, I understand. But if it's empty, it shouldn't take that long. That said, if you don't mind "laid back" service, it is definitely worth a try!
