What customers say

First visit-discovered as we popped in to escape a strong wind. We received a warm welcome and courteous service in a very relaxing atmosphere albeit with limited seating. They serve a great coffee blend and selection of pastries, and I look forward to a repeat visit.

Like this place so much!✨💛 so glad that they have one location in NYC! Pour over was great, I was satisfied with my light roasted coffee. 🍩And I highly recommend their homemade donut! It was not the chewy kind but more like a cake donut. The 🌹rose flavor I got was wonderful😌..

Phenomenal little gem. Excellent pour overs. Darling environment to work, read, hang out. And the pistachio bun is to die for.

★★★★★ — Melissa, 2026-01

Their Williamsburg location is nicely decorated with plants and floor-to-ceiling windows. No doubt this is my preferred location. Their staff were very sweet and passionately recommended me different pastries. *Dirty Chai, Chai Latte Hidden Grounds is known for the variety of chai menu.
