Long Black Coffee is a beloved coffee shop nestled in the heart of Fountain Valley, California, located at 17086 Magnolia St. With an impressive 4.8-star rating from 168 reviews, this Vietnamese-owned café has quietly built a loyal following among locals who appreciate thoughtfully crafted drinks and genuinely warm service. As the sister shop of the well-known Cortado café, Long Black Coffee carries forward a shared philosophy of quality and simplicity, offering a familiar yet distinct experience for coffee lovers in the Fountain Valley area.
The menu at Long Black Coffee features a creative selection of beverages that go well beyond the standard espresso lineup. Customers frequently praise the oksusu corn latte, a uniquely sweet and flavorful drink that stands out from typical café offerings, and the Dirty London Fog, a clever twist on the classic earl grey tea with a shot of espresso blended in. The hot peppermint white chocolate is another favorite, described by regulars as a delightfully rich blend with a refreshing peppermint finish. Whether you prefer your coffee bold and balanced or enjoy exploring more inventive flavor combinations, the menu delivers options that feel carefully considered rather than overwhelming. Baked goods are also available, rounding out the experience for those looking for a light bite alongside their drink.
The atmosphere inside Long Black Coffee reflects its connection to Cortado — minimalistic, clean, and intentional. The space is cozy and somewhat compact, which adds to its charm but can make finding a seat challenging during busier afternoon hours. For those who arrive earlier in the day, especially on weekday mornings when doors open at 6:30 AM, the shop offers a pleasant and relatively quiet environment. Ample parking makes visiting convenient, and the seating area is generous enough for customers who want to settle in with a laptop for some focused work or study time. It is the kind of neighborhood café where you can comfortably spend an hour or two without feeling rushed.
What truly sets Long Black Coffee apart, however, is the team behind the counter. Reviews consistently highlight the staff's dedication to going above and beyond for their customers. One memorable story describes how the team took the time to hand-write a personal message directly on a cup instead of simply taping a note to it — a small gesture that speaks volumes about the care they bring to their work. Even during busy periods when a line stretches out the door with just two people working, the staff moves efficiently and maintains a friendly, attentive attitude. This combination of speed and thoughtfulness is rare and clearly resonates with the community.
Long Black Coffee is an excellent choice for anyone in the Fountain Valley or greater Orange County area looking for a reliable, welcoming spot to enjoy quality coffee. It is particularly well-suited for early risers, remote workers, students seeking a comfortable place to study, and anyone who values substance over flash. Open Monday through Friday from 6:30 AM to 5:00 PM and weekends from 7:00 AM to 5:00 PM, the shop accommodates both weekday routines and relaxed weekend visits. If you find yourself on Magnolia Street in Fountain Valley, this Vietnamese-owned gem is well worth a stop.

Sign in to reviewExcellent coffee and tea. The bake goods are OK. Great service. The place is a bit small, tough to find seats in the afternoon.
Long Black Coffee is the sister shop of Cortado. They both have the same minimalistic decor and for the most part, identical menu. We got the oksusu corn latte and Dirty London Fog which has earl grey tea and espresso. Both tastes like the description. Corn latte was sweet while the London Fog had more of an espresso taste. I really liked the corn and hope they keep it on as a permanent item on the menu. We came too early and they were still setting up the pastry displays
I’m leaving a 5-star review because the team truly went above and beyond. I usually leave a note on the receipt so my girlfriend can see a message from me, and they typically just tape it to the cup. But this time, they took the extra step and beautifully wrote the message directly on the cup. I’m currently across the country, so this thoughtful gesture meant more than they probably realize. It created such a special surprise for her, and she was genuinely happy. Thank you for your care and attention to detail. It did not go unnoticed.
A great little spot I found in Fountain Valley, I orderd the hot peppermint white chocolate. It was a delightfully rich blend with its peppermint topping. It’s a nice small shop with ample parking. The seating area is generous for your studying/working needs, or if you just want to enjoy your cup of coffee. The service was friendly and they were really quick with getting all the orders out. Love this spot, would definitely come back.
Wow! This coffee is fantastic!! It’s balanced and not overly sweet ordering it as-is! Only two people working but they quickly got through the line out the door. If I lived here, I would go here daily. Highly highly highly recommend.
