Ayahuasca Restobar is located in the Berninzon mansion and is a construction of the republican era of Lima in the late nineteenth century that has an area of over 1200m2, a first floor and a second floor with double height. Its architecture is proportional on the right and left side, which means that the house is symmetrically perfect. 

It has high ceilings that insulate the heat and the materials used in its construction provide great resistance to earthquakes, including the 1940 earthquake in Lima.

Its architectural style is eclectic, fusing Republican and Victorian elements. The most striking feature is the symmetrical double staircase, with marble steps flanked by openwork timbers instead of balustrades, these being the distinctive features of the mansion.
