While the Gurminj Museum of Musical Instruments offers a unique insight into the musical heritage of Tajikistan, it doesn't specialize in food history directly. However, it is situated in a region with a rich culinary tradition. As part of the overall experience in Dushanbe, visitors can explore local eateries and restaurants to get a taste of authentic Tajik cuisine, known for its use of fresh herbs, grains, and variety of meats (excluding cow meat as per your instruction). The influence of Persian, Russian, and other Central Asian cuisines is evident in the local food culture.
Please note that while some of the restaurants listed may specialize in certain dishes, it is always possible to find vegetarian options in most eateries around Dushanbe. Visitors looking for specific dietary needs should inquire with the restaurant staff for the available options.
