Delicious! My husband, who is Peruvian, felt this was authentic. Only downside would've been that they were understaffed. It's not a big place, but once it filled up, the one waitress was running. Also, parking is limited, which is typical for DT Phoenix. Highly recommend trying at least once. Our favorites were: Lomo saltado (beef with French fries and gravy-like sauce), papa rellena (stuffed potato), tallarin saltado con carne (tenderloin with spaghetti) and of course pisco sours!
