My wife and I went here for our 1 year anniversary. We initially thought, based on the pictures online, that it was a bit less casual than it turned out to be, but that was not an issue. The restaurant has mostly tables with a DJ booth in a corner and a bar to one side.
Our waitress was attentive, speaking to my wife in Spanish, and helped us choose an appetizer. The food was delicious! Our ceviche was really top-nop and came in a huge portion. Our main dishes were simple, unpretentious, but deftly executed and tasty. My fish came with a 'seafood' sauce that turned out to have mussels and perfectly cooked octopus in it. All in all, it was fantastic. Great Peruvian cuisine in a casual environment.
