Die besten Restaurants mit Steakhaus Essen in Waldshut-Tiengen

I've eaten in this restaurant a few times and it's always been good, but recently the owner has become quite cheeky. Even though we had traveled there from Switzerland and arrived quite hungry, we were told that they didn't have a reservation for us. Although I had reserved online (confirmation email 'sent' available), I didn't get a confirmation (confirmation from 'el milagro', which makes me wonder why? We asked politely if we could still get a table, which the shop owner immediately denied , although there were a lot of free tables available. We suspect that he didn't want us there because we were foreigners. Well, it seems that he has enough customers for me and my companions I'm sure that we won't be eating there anymore and I'm asking others to boycott this place... no one has condemned such treatment. I will also advise other people in Switzerland not to go to this place.
