Tried this one with a Peruvian friend who was able to confirm that the food was A-OK and the Pisco Sour cocktails quite good, enough to remind her of her native country. I liked the food and the overall ambience.
The service was spotty, but quick to correct mistakes. However the main drag of this place is the painful noise level, driven by the in-house band singing Happy Birthday songs at just about every table, with wireless mikes and amplified guitars... And they can go on for two hours straight without a pause :)
So, be warned: don't go there if a meaningful conversation needs to take place.
