Bisingen is celebrating: the reopening of the Diamant restaurant on July 9th!
On July 9, 2025 the time has come: the “Restaurant Diamant” opens its doors in the former “Gasthof Adler” in Bisingen-Zimmern. Adna and Kenan Ahmetovic as well as Adna's parents, Adnan and Anela Alijagic, and her brother Adnan Alijagic junior have joined forces to revitalize the region's gastronomy. The name “Diamant” is reminiscent of the family’s former glass business in Bosnia and is intended to be a symbol of quality and value, especially at a time when many restaurants in rural areas have to close. According to Schwarzwälder Bote, the opening is a ray of hope for residents, as good dining options are becoming increasingly popular in the area rare.
The former inn has retained its place in the region's dining scene and could now thrive again under new management. The offering includes traditional German cuisine based on popular classics such as steaks, salads and schnitzels. The price range per person is between 11 and 20 euros, making this restaurant an excellent choice for families and couples who enjoy dining out. The Google rating of 4.5 stars speaks for the quality of the house Restaurant Guru.
A focus on quality
The team around Adna and Kenan Ahmetovic appears to be well prepared for the new challenge. A professional and friendly staff creates a welcoming atmosphere in which guests can feel comfortable. Among other things, the restaurant will also offer outdoor seating and take-away options - particularly appreciated by visitors in a hurry. In addition, the restaurant is barrier-free, which makes access easier for people with mobility restrictions.
Gastronomy is changing
Gastronomy itself has changed significantly in recent years, and the industry still plays an important role in the German economy. In 2022, according to Statista, the catering industry generated sales of over 67 billion euros - a new record. The typical German cuisine, which will also include that in the new Diamant restaurant, continues to be very popular. Around 60 percent of couples, young adults and families eat out regularly and value the opportunity to try new things.
At a time when demand for sustainable and vegan options is increasing, the restaurant also has the potential to respond to these trends. How the industry will develop remains to be seen; However, one thing is certain: the Diamant restaurant opens a new chapter in Bisingen-Zimmern that combines both tradition and innovation.
