We arrived before the evening rush, around 4 p.m., so we were able to choose a seat. After 5:30 p.m., many places were reserved.
Due to accessibility issues, we sat on the terrace/beer garden, which is very nice and set back from the street.
The food and service were excellent. Even a request (vegetable sticks for our child) was accommodated free of charge.
Right at the beginning, we were asked if we wanted the vegan or gluten-free menu. Desserts also offer similar options, so there's something for everyone without having to explicitly ask.
