Althought Mayan, Aztec and Inca are very similar cultures, especially when it comes to their gods, the restaurant is peruvian, the decor is peruvian. Source: Im peruvian and I love the restaurant, the staff is pretty great and helpful
Google does not know the difference between Maya and Inca. It is actually an Incan setting.
The decorations are very Mayan themed. But I wouldn't go as far as calling the setting Mayan.
