What customers say

The coffee here was great. We have been a big fan of their beans for many years and enjoyed coming to the shop. The cold brew and black coffee were excellent. The croissant was good but I have tasted better.

Onyx Coffee Lab in Fayetteville deserves every bit of its five-star reputation. Conveniently located with plenty of parking, it’s easy to swing by and settle in for a delightful coffee experience. From the moment we walked in, we were greeted by a clean, welcoming atmosphere that just felt good to be in.

Loved it. Onyx was a bucket list coffee for me and I was excited to check it off the list. No regrets. I ordered a cappuccino and a double shot sidecar. Smooth espresso that was really well balanced. Highly recommend getting a shot on its own.
