Hands down the best quality coffee experience I’ve ever had. The tasting notes are intentional, the execution is flawless, and the baristas are true craftsmen behind the bar.

Absolutely loved my visit to DEX Coffee. The atmosphere is warm, cozy, and beautifully designed with a high-end, thoughtful vibe that makes you want to stay longer.

New favorite place unlocked 🔓 Nice atmosphere, great service. You cannot just get one drink here. I’m a big matcha lover and they have so many matcha flavors. Tried the butterscotch matcha—SO smooth, and the matcha pairs perfectly. Already had coffee this morning, but that’s my next to-go order when I come back. Walking out with a hojicha though 😌🍵

I really enjoyed their Dex Delight Matcha which has a unique + pleasant cinnamon flavor. Their regular matcha latte was also good! The matcha was very balanced and not bitter. It was also a great study space with chargers and comfy seats.

Omg! First time here and totally coming back. I tried the cardamom latte, with orange cream top. Absolutely delicious, and aesthetically pleasing. The young man who helped me at the counter was very patient with all my questions I had on the menu, I really appreciated his etiquette and customer service. Shoutout to him! And this coffee is wonderful.

By far one of the BEST coffee and matcha spots we’ve ever been to. Dex Coffee is the kind of place that immediately makes you want to slow down and stay awhile. From the moment you walk in, you can feel how intentional everything is — the warm aesthetic, the lighting, the wood details, the indoor and outdoor seating, and …

Such a cute little coffee shop. The interior has a really cozy, stylish vibe with warm wood tones and a clean, modern setup. You can tell they put thought into the details, from the pastry display to the drink presentation. The coffee flavors were unique and really flavorful. I got the hazelnut latte and it was smooth, rich, and perfectly …
