Classy atmosphere. Nice to relax there. I had fingerfood. Amazing!

Most of the time we only go to Onyx because of Samantha, you rarely get such good and warm service anywhere! It's about time for a raise! She is doing an phenomenal job!

A good and trendy place located on the ground floor of the Park Hyatt hotel. A bit pricey, but "normal" for Zurich :-// Friendly staff and a good selection of drinks and fingerfood

Simply perfect atmosphere, chic, drinks and food, all made with lots of love and perfection. The staff was very pleasant, the music was very cozy. A piece of oasis in the heart of Zurich for great tasters. Delicious Mojitos, fresh beer! Just yummy ...

Great service, awesome cocktails. The place was mostly empty (Sunday evening in Zurich..) so the staff was very alert and the ambience was very relaxing. Will definitely come again.

Was there last night, music was so loud that you could not even talk to each other. Empty tables with glasses and people outside smoking, so you could not even see if the table is free or not. Service lady told us its all full and we could not get a table.

Amazing experience! Luxurious servive as always. Its simply great! I loved Laurence. He is simply awesome!!!!!

High quality cocktails. The staff was amazing. They really know what they are doing,.

This is the best bar you can find in Zurich with great music, unique cocktails and an amazing service team. They will make your night becomes 10 times better. To Lorenzo, Arnel, Cheyi, Daniela, Marco and Angusha, I love you all so much and I will never forget the nights with you all. ❤️

I've been here a few times. It's nice and chill, service and the drinks are good. Nothing to complain about.

Eddie was great, very helpful and knowledgeable. Cigars looked awesome 👍.

The ambience in there is very smooth and elegant. The service is really good and the drinks are awesome. A cool place to visit! No doubt one of the best bars in Zürich!

Very cool and trandy, nice music, excellent Drinks

Really good drinks and some cozy lounges. Perfect for the widely known “classical” drinks/cocktails with your favorite exclusive spirit/liquor.

Great experience with DJ, great food and amazingly friendly staff.

Friendly staff, good drinks and proper interior design. Perfect for an after shopping drink or afternoon coffee/tea. 4 stars because there is nothing "outstanding" to be mentioned.

classy bar. expensive, not surprisingly

A bit pricy but great drinks and very friendly staff.

Elegant and nice place to have cocktails and nice whiskies 🍹

the drinks are really good and the snacks are very delicious

Easily one of the best locations Zurich has to offer. As always, the Hyatt never disappoints. No matter where you are. Amazing selection of drinks. Beer on tap is very good. Pleasant atmosphere and really nice staff.

The new lady (i guess Francesca was her name) did an excellent service and made us stay longer than we have should! very kind and just so talented at what shes doing wow!

Bar onyx staff very bad service looking and make people uncomfortable instead of bringing the right orders, they make fun of clients. Mind your business instead of listening clients discussion. Thank you
