Translation of exorbitant in German

Anyway, we left, as everybody else was leaving and once outside we understood that most people were just crossing the street in order to enter into this other night club. So did we.
We had dinner in a Chinese restaurant not far from where we slept, but it was not good at all. We walked home and slept early. The coming morning we were picked up on the backpackers' street.
The next day we had the feeling that the worst of our altitude thickness was over and decided to take the local bus to the Sacred Valley, a key area of settlement to the Incas.
