There is a restaurant/cafe behind and to the east of St. Lorentz church that is good and not frequented by tourists. We were told of it by the people at Hotel Drei Raben. The food was good (although I'm no foodie) and it was busy. I believe it was called Cafe Lorentz.

The place didn't have any English menus. The lady (hostess?) was very apologetic and kind of funny about it. She came over to our table with the German menus and a book which turned out to be a translation book for mainly food items. We were pretty easy customers and it only took a minute.

Considering the location and size of the place I'm surprised it isn't frequented more by tourists. I guess it looks more like a business lunch place.

We were there last December so I only remember the Christmas Market. It was huge (actually seemed too large).
