What customers say

It’s been a dream to come to an official Oynx cafe and it was wonderful! The layout was open and welcoming. Love their seasonal fall menu- I decided to have the black sesame maple espresso and the vegan egg focaccia. I enjoyed the chill temperature of the drink. It was smooth and flavorful.

This is the best coffee place in town. No second thoughts. Me and my fam have gone here plenty of times. There was never once disappointing. I loved all their coffees. I would love to explore so I tried almost 85% in the menu by then. Let me brief a bit.

We visited the downtown square store. It's huge and beautiful, like a Perth coffee straight out of a memory. It was very busy, and we had to queue to order. We ordered two seasonal specials: 💕tiramisu fomo (less sugar) 💕fig citrus nitro tonic Both were delicious.

⭐️⭐️⭐️⭐️⭐️ Onyx Coffee Lab in Bentonville is outstanding! The service was fantastic—Sarah was especially awesome, making the experience feel warm and personal. I ordered a Cortado, and it was incredibly smooth and velvety, served with a classy sidecar of sparkling water that elevated the whole presentation.
