Really cool little coffee shop built out of an old warehouse. While the facade has a rusted patina, the interior is gorgeously maintained and has a very cool minimalist design. The shop has some outdoor seating, bar seating, and booths. There is also a free water station for you to use. The coffee I’ve tried here has all been exceptional. The two cold brews I’ve had—Gichata and Uraga washed—were both really nice, though the Gichata’s lemon meringue flavor really stood out! The espresso I had was also very complex and delicious, with a deep and smooth flavor. I’ll have to try some food from this spot, but overall I really love it! It’s down-to-earth yet sophisticated, and the product is perfect for casual drinkers and aficionados alike!

What a nice cafe! The waiters were so nice and spoke English! The coffee was really good but they also had a really nice meal, so tasty! Perfect place for brunch! And the atmosphere there is also cosy!

Tucked inside a warehouse in Ryogoku, Single O is a hidden gem for coffee lovers. The industrial setting gives it a cool, laid-back vibe, perfect for chilling or getting work done. The staff are super friendly and know their coffee well. A great spot if you’re looking for good brews and a relaxed atmosphere off the beaten path.

The coffee is DISGUSTING. It was so sour and bitter that we couldn’t drink and left. :( Its also very overpriced (1900 jpy for one normal one decaf latte) and took a very long time to come. Really disappointing, spoilt our Sunday coffee joy

A pleasant find after walking around in the hot summer weather. This coffee place has really chill vibes and the baristas are friendly and kind. I felt immediately comfortable and relaxed upon entry and they welcome each guest with respect. The quality of their coffee and light bites is high. We had the jaffles, carrot cake, iced latte and iced matcha. Their matcha here is delicious. A great pit stop to rest and relax. They have all sorts of special brews if you’re into that. A nice chill out place to have a small bite.
