Translation of empirical in German

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.
On day two my wife and I took a tour to visit the Altiplano. The tour started a little boring, when we visited a few empty villages nearby which were all pretty much the same. Empty with very little people.
