The atomsphere of the restaurant was upscale on the first floor, but seating upstairs was kind of dingy and isolated. My friends and I are very much into Peruvian food but were not thrilled with this restaurant. We've heard many great reviews of Picca from friends and were very excited to go for dinner, but as soon as the waiter came around, he wasn't the nicest. He asked if we were familiar with Peruvian food, so we said yes and my friend mentioned how he is actually Peruvian himself. The waiter said "so?". We thought he was joking at first and there was a minute or so of awkward silence when we realized he was serious and just plain rude. He proceeded to describe the menu and give us his recommendations.
The food was ok, not that great, and didn't really have flavor at all. The lomo saltado didn't have much taste and I was disappointed (it's my favorite Peruvian dish). When he came to bring us the bill, we looked it over and found that he charged us the 20% gratuity for 6 people, while we were only 5. We pointed out the error and he apologized and corrected the bill. If we didn't pay attention to the breakdown of the bill, we would have given him an extra tip, not knowing it was already added in.
All in all, we didn't have a great experience and probably won't return next time we're in LA.
