TLDR: Rude and odd service, especially if you're an English speaker, but food is good.

Full information: On Saturday 25th March, myself and two friends visited Ach'i to celebrate one of my friends’ birthdays. We sat down in our seats, ordered our food and began eating our meals. The food was great – no complaints there. My friends and I all talked and laughed together. The noise in the restaurant was loud in general with other people also talking and laughing amongst themselves. We naturally had to talk louder than usual to hear each other speaking, just like everyone in the restaurant. Abruptly and in not a nice way, we were told by the waitress that we were being too loud. All of us were speechless and confused... In a full restaurant that was very busy and already so loud? We were English-speaking people, surrounded seemingly by those who were speaking Swiss German, so we felt discriminated against for our language as no others were approached. Perhaps our voices stood out more, but it felt more about us being stereotyped as "loud English speaking expats". Also, being told to be more quiet (although it didn't make sense), could be acceptable if at least it was raised in a respectful and considerate manner. Then to make matters worse, we were VERY rushed out of the restaurant. My friend was just about to open her birthday presents at the table and the bill was already placed in front of us without us even asking for it. The waitress then proceeded to clean the table and put four new menus down right in front of us as we sat there (pushing around the gifts on the table). Then she brought in 4 new people to sit at our table and just had them stand next to us awkwardly while we were not even done. We had booked the table in the first place and it had only been an hour or so (nothing long)! We found this very rude and we were treated poorly. We were overall very disappointed about the service here, we felt so uncomfortable, especially as we were there to celebrate my friends’ birthday. We couldn’t even talk to hear eachother well and we were rushed (basically kicked) out. I wouldn’t recommend this restaurant to any expat, especially if you speak English. They seem to have a huge problem with it.
