During the time that we spent in Frankfurt, we enjoyed a wide variety of restaurants, especially French, Italian, and Thai restaurants. Because we went out for lunch and dinner almost every day, we looked for places to eat that were located around our apartment where the staff was friendly, the food was good, and the atmosphere was inviting. There was a restaurant near the underground train station that we used almost on a daily basis that became our go-to place to eat and have a glass of wine. The restaurant was called the Brasserie, but unfortunately it closed down shortly after we left Frankfurt.
Located next to Alte Oper (the old opera house), the Brasserie was basically a French Bistro with fresh food of the finest quality. We enjoyed many wonderful meals at the Brasserie, but probably our favorite meals would have been the plate du jour, which obviously changed daily. Like many European restaurants have a somewhat limited menu, but everything we ate there was truly delicious. The meals were not particularly expensive, despite being in the heart of the tourist area and only about a ten-minute walk from our apartment.
