Review of Hollerbach's German Restaurant

I asked for a sausage with red cabbage, and a side salad, the salad arrived with a piece of wheat bread on the side (I asked if it was GF bread and it was"t), the waiter returned the salad and brought a new one, which I did not touch at the end ( too risky). I had no issues at all with the sausage and red cabbage , meaning ir was really GF.
