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. I tried the matcha latte, hojicha latte, and a waffle, and everything was balanced, smooth, and really well-made. The staff were incredibly friendly and attentive, which made the experience even better. It’s rare to find a café that feels this stylish yet genuinely welcoming at the same time. Highly recommend DEX Coffee for anyone looking for great drinks, great service, and a space that feels both comfortable and premium. I’ll definitely be back.

Went on Christmas Day, somehow the baristas where happy to be there. If I could rate 6/5 stars I would Coffee : Well priced very smooth strong espresso (barista was right it's bold) I got the Dex latte and it was 5/5 My dad got a decaf latte with oat milk and noted it had more flavor than a normal decaf and he was surprised. Environment was super nice and clean, plenty of seating, couch is very comfy. Shop is unique and uses soft lights Yes we got free socks on Christmas

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.

1. The coffee drinks were both well-crafted! I really like the orange hojicha drink! 2. The spot has fun casual vibes! The interior was nicely arranged! 3. The staff was friendly and timely with my order! The drinks were ready in less than 10 mins! Note: There is a single restroom available for customers!

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 even the bathroom being beautifully designed and thoughtfully maintained. Every part of the space feels elevated yet welcoming at the same time. It’s also such a great spot to work or study. They provide Wi-Fi, there are plenty of outlets throughout the space to charge your laptop or phone, and the overall atmosphere just makes you want to stay productive while still feeling relaxed. What truly sets Dex apart, though, is the QUALITY behind everything they serve. You can genuinely taste the difference. The fact that they use organic ingredients and prepare things fresh daily speaks volumes about the care they put into their craft. As matcha lovers, we especially appreciated their first harvest, ceremonial grade matcha from Uji, Japan — absolutely incredible! Their pastries are also delicious, and I even brought home one of their ceremonial-grade matcha jars to enjoy at home, which has been amazing. We’ve now tried many drinks from Dex, and honestly… every single one has been so good. Some of my personal favorites are the Strawberry Matcha Latte, Banana Matcha Latte, and Blueberry Matcha Latte. The Orange Matcha Einspanner is also AMAZING and such a standout drink. We also loved the Pear Matcha Einspanner, which was super unique and unlike anything we’ve tried before, along with the Coconut Matcha Einspanner, which was equally incredible. Other favorites included the Maple Delight Latte, Toasted Caramel Latte, Dex Delight Matcha Latte, and honestly all of the pastries as well. I also love that they offer thoughtfully curated products beyond the drinks themselves — from their matcha and hojicha to their branded hats and merchandise. You can tell th

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 balanced, not overly sweet. The matcha was also really good, fresh-tasting and well made. Service was great too. Friendly, quick, and welcoming. The only downside is that it’s a bit small inside, so seating can be limited, but that also adds to the cozy feel. Overall a great spot for quality drinks and a relaxed coffee run.
