Authentic. Great service. We even talked to the chef/owner & he is such a nice & genuine guy. We loved this place & my parents grew up in Peru so we have very high standards for Peruvian food. We loved the papas rellenas and the yucca was great! Lomo Saltado was delicious! We also ordered the aji de gallina & it was good but not like my moms :) The fried sweet bananas were to die for! If uou go, you have to get inca cola its a yellow soda & its so good! We will def be coming back & bring more people!
