Following a rather disastrous experience when eating out with the family (they're visiting from Spain) the day before, this place has made our week!
We were somewhat late for lunch by German standards and were still welcome to take a seat in the outdoor terrace that is bordered by what I think is a part of the historical town wall. What a beautiful place to sit in the historical town of Marbach!
If I got it right, the place is run by a middle aged couple. Rather than talking about "service", I'd like to compare this as being for lunch at your aunt's who does really good home cooking and is taking special care to make things just right for you. It's not the sleek choreography they exercise at hotels, but it certainly has it's charm.
The food is very good home cooking, we had authentic home made Maultaschen (with lots of meaty filling and easy on the veggies; those were certainly made from scratch!) and duck breast on sautéed beets and corn frittatas. Dessert was really good, especially the home made ice cream and sorbet.
The price point is very reasonable, as the quality and preparation of food was quite excellent. We really did enjoy our lunch there very much!
