Restaurant Sanchez - Rincon Latino

We were super excited to have found a Colombian restaurant here in Germany since we are Colombian. However, we traveled for almost 1 1/2 hours to go to this place, on a saturday and it was closed!!! The hours in the website said that it was supposed to be opened from 5 pm - 1 am, and we got there around 7 pm. There is no sign in the door saying anything whatsoever. It looks like the restaurant went out of business or something. The website says that the website is under maintenance, but that the restaurant is opened. We were really upset to have traveled all the way there, to turn around and go back!!
