"Lovely little coffee shop in Costa Mesa. They have a lovely selection of pastries and breakfast burritos. We tried the elote pastry and was delicious. It was sweet but not too sweet which complimented the cortados. Service was quick and prompt. If you enjoy a quiet and colorful coffee shop, I would recommend visiting Buenas"

"Drive by on a Saturday and they were open! Wasn’t busy, so it was perfect for a quick snack before my appointment I had down the street. Walked in, was greeted by the three workers, so sweet. They helped me pick a yummy baked good, I chose the homemade vegan brown sugar pop tart by a small biz in Long Beach. Soooooo delicious. Wasn’t too sweet. I got the cold brew with the sweet corn foam top. The cold brew was smooth and not bitter at all. Seats onsite and easy parking. Industrial lot."

"Consistently Great Flat Whites in Costa Mesa If you’re serious about coffee, Buenas in Costa Mesa is a must-visit. Every time I come here, the flat white is consistently phenomenal—smooth, rich, and perfectly textured. It’s clear they care about their craft, from the quality of the beans to the precision in steaming the milk. A Fun Touch: Latte Art on Hot Chocolate The kids ordered hot chocolate, and what made it extra special? They actually did latte art on it! It’s such a thoughtful detail and adds a little magic to a simple drink. Why This Spot Stands Out Beyond just great coffee, Buenas has a welcoming vibe that makes it a perfect stop, whether you’re grabbing a quick cup or lingering a little longer. If you’re in Costa Mesa and love well-made coffee, this place should be on your list."

"Service was great, loved how they served pan dulce. Servings are small and misleading. Maybe have a sign that discloses this for us girlies who don’t know about real coffee servings 🥹 one size does not fit all."

"Super nice people, strong+hugh quality coffee...love the inside and the outside seating. I especially enjoyed the Patrick cortado with brown sugar!!"
