While Budapest still has a sizeable Jewish community, there are only four kosher restaurants and just a single kosher pastry shop in the city. They're all within the old Jewish Quarter, near the Kazinczy Street Orthodox Synagogue. Carmel and Hanna are meat, whereas Kosher Deli and Tel Aviv Café are dairy restaurants. If you don't keep strictly kosher, you could also try these Jewish-style, but non-kosher restaurants.
Managed by the Hungarian Chabad-Lubavitch Hasidic community, Carmel is one of Budapest’s few glatt kosher restaurants. During the meals a mashgiach—an official supervising rabbi—is present at all times to ensure that Carmel adheres to kashrut, the Jewish dietary laws. As is the case with Hanna, the other meat restaurant around the corner from here, Carmel gets liveliest during Shabbat, that is, Friday's dinner and Saturday's lunch. Here too, guests must prepay the meals, each of which costs €25 per person.
