Translation of atheistic in German

The four of us ate dinner at this cozy place. As always, we ate meat. After desert we headed to a night club, when my wife started to feel a little dizzy. She blamed the wine, but i had a bad feeling.
We decided to walk back and explore the city on foot. It was hard to cross the streets as there was an endless flow of motorcycles and bikes. One needed to just enter the street and cross it.
We visited the Inca Ruins on the mountains near Pisac: A taxi took us to the top and we walked all the way back down to Pisac (which by the way is not an easy task on day 2 at this altitude)
