"Saw this viral bakery on Instagram and got to check it out. The location is in prime downtown area of Castro valley. We got there 30 mins before closing and was surprised that they still had a lot of options left. There were a lot that I was curious about, but we ended up going with the lemongrass chicken croissant and pistachio croissant. Lemon grass was very delicious. It was chicken thigh and seasoned very well. I wish the chicken was shredded because there were bites that didn’t have chicken in it. Pistachio croissant is filled with pistachio cream. I liked it alot and would recommend trying this. Coffee selection was limited at the end of the day. The orange latte was very good. Love this spot and everyone should try One’s Cafe!"

"Hidden gem in Castro valley Cute lil coffee shop and their coffee is smooth and hits the right spot. If you come earlier in the morning you might even see plenty of pastries. Next time, I will plan to come early and try their pastries. So happy to see mom n pop coffee shops open up in CV. This is the new Hayes Valley of the east bay!"

"Their laminated pastries are works of art, so creative both visually and flavor wise, incorporating asian elements like black sesame cream and lemongrass chicken. Although the interior is small I love the outdoor seating when it’s warm outside! I will definitely be back."

"This is an amazing cafe/viennoiserie. It’s small and unassuming, in a non trendy location. If it was in SF, lines will be out the door. For me, it blew Tartine out of the water. Food reviews are subjective in its nature and although some might disagree with that, you will know immediately this place is serious about their craft. Orange and vanilla lattes are amazing. Regular latte is also very rich and dense in the best way possible. Orange latte is out sometimes, but I highly recommend you come back and try it. I tried several pastries here and all were buttery, flaky, luxurious goodness. Black sesame Onigiri and strawberry moon were excellent. I thought there weren’t a lot of chocolate in chocolate croissant but somehow it was right amount once I tasted it. It’s also relaxing to watch barista going through rituals of espresso making without rush you see in most coffee shops. I’m kinda impressed about this place. I was excited to come and try and it exceeded my expectations. I come here regularly now."
