"If you are a matcha lover, highly recommend this place! It’s so hard to find good quality matcha out at a shop. I had the mango matcha, which can be hard to master since usually one ingredient overpowers the rest. Dayon’s matcha was rich, smooth, and not overly sweet. The mango was subtly sweet and complimented the matcha perfectly. I look forward to trying more things on their menu! Go support local and small businesses like Dayon! ☀️"

"First time in San Diego, came here 10/11/2025 and they gave the best customer service providing me recommendations and making sure I was comfortable with the milk options. Prices are very reasonable with how delicious the drinks taste. I got the Ube Cream Top Matcha large, it was the perfect amount of sweetness and Ube flavor. Salamat Po Tita! (I also highly recommend the Ube bread!! So soft and flavorful!)"

"Oceanside now has a new Filipino café. Dayon Coffee Co is a small, family owned coffee cart that is located just north of the 78 highway and near the building of 5.11 Tactical. Because Dayon Coffee is operating out of a yellow coffee cart, they are situated within a rarely used parking lot, and you must look for their yellow flags by the road entrance. They have managed to create a nice atmosphere with some chairs and tables and will soon be adding some fencing and other decorations to make it cozier. The service is friendly and they have patience with all my inquiries. Dayon Coffee Co serves many delicious Asian and Filipino inspired flavors on their menu. They are known for having Ube pastries & coffee, as well as Matcha and other unique flavors for their lattes. They also have a variety of lemonade drinks, and they also have the capability to order online and a reward program. I recommend their seasonal special drink known as "The Dirtbag", which contains a flavorful blend of Oreos and Ube. Surprisingly, customers even have access to use of the restrooms that are located in the 5.11 Tactical store that is in the same parking lot. Overall, I really enjoy the variety and flavors at this café, and I also appreciate supporting a small family business."

"First time here and I got the Strawberry Matcha Cream Top and Ube Crinkle. Both were so delicious! The drink and Ube Crinkle was not too sweet, which I love. Highly recommend this place!"

"Dayon Coffee is such a gem! It opened near my home a few months ago and has quickly become my go to spot. Their Banana Latte is amazing, and the chocolate s’mores cookie is the perfect treat. Even though I have plenty of big coffee chains nearby, I always choose Coffee the quality and taste are unmatched. Plus, it’s the only coffee that leaves me feeling energized instead of sluggish. Highly recommend!"
