Since I come from the restaurant industry myself, it shocks me even more.
I fully understand that when tables are reserved, they don't get filled – but!
I find it outrageous that the only restaurant that serves gluten-free dishes, and that I can visit despite my celiac disease, treats its guests like this.
In the restaurant, we were told that unfortunately, there was no room left (we noticed her looking at the free table).
Unfortunately, there was nothing we could do, so my pregnant wife, and my three-year-old had to leave the restaurant.
15 seconds after us, three girls arrived (one more person), who also didn't have a reservation, but were seated immediately. They announced at the door that the place looked very full and they certainly wouldn't be able to get a seat.
That was the last time I visited the restaurant.
