Black Sheep Coffee - Great Portland St in City of London, Westminster

I’ve been to this location a few times(Great Portland Street), but unfortunately, my recent experience(12.4.2025 at 10:35am) left me very disappointed. My friend and I ordered Dirty Chai Lattes via the app, and while my friend’s order was ready quickly and tasted fine, mine was another story. For the second Saturday in a row, my Dirty Chai Latte had no hint of chai or coffee—it tasted like plain hot milk. I decided to return it and politely ask for a replacement. Unfortunately, the barista (a young man with a scar on his eyebrow) responded in a passive-aggressive and defensive manner, insisting there was nothing wrong with the drink. Thankfully, a female staff member stepped in and kindly offered to remake it. During the process, the original barista grabbed a bottle of chai syrup from the shelf—apparently the one he had been using was empty, which likely explains the lack of flavor in the first drink. He then added an excessive amount of syrup and made intense eye contact with me, which felt unnecessarily confrontational. To make things worse, he forgot to add the coffee entirely, resulting in an overly sweet drink that was even worse than the first. At that point, I decided not to continue the conversation in-store, but I will be contacting the general manager to report the experience. It’s incredibly frustrating to pay premium prices for a product that’s poorly made—not just once, but twice—and to be treated with hostility when raising a genuine concern. I hope the management team addresses the quality control and staff training at this location, as this kind of experience reflects poorly on the Black Sheep Coffee brand.

Just paid £4.58 for an almond cappuccino! The place it’s nice but some of the highest prices in London. At least it’s good!

We stayed in London for four nights and visited the Black Sheep every morning for our caffeine fix. We were/ are early risers, so we were standing outside waiting as the staff were opening. All the staff were so very friendly and amazing…even at 6am! The coffee was very good and consistently good every morning…we were lucky to have them so close and opening with smile so early!! Thank you!!

The pass it forward coffee scheme is a great idea especially as a student! The staff are wonderful and friendly and it’s such a great comforting vibe inside! - a must visit for everyone who loves coffee!

Lovely bunch, made me smile on what was a pretty crap morning! Good coffee too, highly recommend! 🕺🏾🕺🏾🕺🏾🕺🏾🕺🏾🕺🏾🕺🏾🕺🏾🕺🏾🕺🏾🕺🏾🕺🏾🕺🏾🕺🏾🕺🏾🕺🏾🕺🏾🕺🏾🕺🏾

De lejos, mi café favorito. . ¡nada se compara! Black Sheep tiene múltiples ubicaciones alrededor de Londres, grandes y pequeñas, perfectas para ponerse al día, solo o simplemente sobre la marcha. Podría escribir una reseña completa sobre lo bueno que es el café y lo hecho constantemente a la perfección, pero esta reseña está dedicada al amable personal que siempre me anima sin importar cuán temprano en la mañana o cuán gris y lluvioso pueda estar afuera. Su energía positiva me despierta antes de tomar el primer sorbo de café, lo que hace que mis desplazamientos matutinos sean siempre algo que esperar.
