My wife and I went here recently for a lunch break during an afternoon of touring the town. The service was slow and almost non-existent, my sausages were undercooked (bloody)and the quality of the meals was very poor.
To add to this, although we ordered beer with the meal, they charged us TWICE for glasses of tap water.....E2.10 each!! ($3!!) I guarantee that this is not standard practice and they were just ripping-off tourists. People like this do not deserve to be patronized by you as, if your reading this, I'm sure you plan on being a tourist too.
Rothenburg ob der Tauber is an amazing place however, and we strongly advise visiting the town.
