★ 5★ 4★ 3★ 2★ 1This coffee shop is an absolute gem! ☕✨ They serve real, high-quality coffee that they roast themselves, and it’s honestly one of the best cups I’ve ever had. The fresh pastries are always delicious, and the cozy, welcoming atmosphere makes it the perfect place to relax or catch up with friends. Highly recommend if you’re looking for amazing coffee and a warm vibe!
August 27 · Vladimir “Bukharoff”never thought I could be impressed by a cafe in 2025, but here we are, zhou pastries and lattes in this shop. sent this to my favorites cafe in the neighborhood. the turmeric latte with almond milk Kat intensely interesting flavors, and the Belgian hot chocolate was well balanced and the sea salt chocolate cookie was crisp and delightful, and all of the food was the right balance of not too sweet so all was thoroughly enjoyed, will be back. also to note, there was a good atmosphere of a lot of people sectioned off in one area doing work or the others area socializing and it offers a good variety for neighborhood goers coming around and offers a bite to eat like salads if you are interested
April 27 · Michael ChengOverall fantastic place. Great drip coffee from house roasted beans, delicious salads and sandwiches, mouth-watering banana bread.The staff are friendly and gladly answer any questions about the coffee or food.The atmosphere is inviting with a corner location, huge plate glass windows, lots of seating, including fishbowl stools overlooking the 5th Ave sidewalk. Comfortable outdoor seating in warmer weather, on the eastern side of the street with morning to midday shade.Yes, the wait time for food on weekend mornings can be up to 30 minutes, but the staff give you a heads up on the estimated time. So not a place to go if you're in a rush, but a fantastic place to go if want to linger at a table and enjoy a leisurely coffee and brunch.I happened to meet the owner one day as she was sitting outside with a friend and a group of girls. It's telling to see someone outside of their work role, and she was delightful and skillful with this energetic group of girls.
August 13 · EliseoI was really excited to try this cafe after walking around park slope. The menu looked really good and the atmosphere was great but the service was not. The staff was not friendly and made me feel like I was bothering them when I asked for a to go box. I decided to leave shortly after because it just didn’t feel like a welcoming place. Maybe I will try it out another time but it just was not a good first experience.
August 27 · Nichole ByronLove this cafe! It’s clean, good vibes, and usually easy to grab a seat (or short wait). I looove the food and the pastries are delicious
