Dear food critics: Just because it's "authentic" doesn't mean its good. The food at this place is not that inexpensive given the typical quality of the ingredients of Peruvian cooking, and they seem to cut corners on some of the ingredients at that. For example, $9 for a soupy ceviche that uses tilipia, which was (surprise!) mushy. The shrimp soup ($7) is OK but almost all liquid. Some of the desserts (e.g., the $1.25 cookies) are a bargain. From what I have heard from other diners and by the appearance of the dishes, the meat entrees aren't so great. For just a little more money, you can do better at the nearby Flor de Canela or the place in Arlington, for example, and almost anywhere for ceviche. If I ever return, I'll probably try the chicken and another dessert (epecially the one they advertise on the menu but say they haven't started making yet!)
Bottom line: It's worth a try, but don't expect too much. Even the best Peruvian restaurant food, at least those few I have tried in the DC burbs, is inferior to what a halfway competent home cook can do, particularly if they really wanted to cook tripe or beef hearts.
