After Costa shut down. Started going here. I must say the Caramel Coffe is amazing here. Staff are also friendly and the atmosphere is really chilled. Some seats are really comfy too.

Would love it if the coffees were a little bigger but that's just because I love them so much.

Been looking forward to going here due to the reviews. Went Sunday and was disappointed. The staff were friendly. But it was a roasting hot day and there was no air con or anything. The temp inside was so hot and uncomfortable. Ordered a v60 pour over and was sad that the coffee was bitter and not a good taste at all. And for nearly 4 pounds. Won't be going back unfortunately

Mocha did not taste like a mocha at all. Not chocolatey even though they say it’s made with real chocolate. Definitely need to use more chocolate in the serving. Sizes of the drinks are ridiculous too, £3 for a very small drink.

When I told the staff that my drink wasn’t up to scratch they seemed very frustrated with me and didn’t want to remake the drink.

Definitely would not go back

No savory food available when visiting the café. And a particular staff member with red hair (Katia perhaps?) was exceptionally rude when I had my own sandwich. Even though both my partner and I had each spent £3.50 on hot drinks that were very small, about 160ml cups.
I wouldn’t have even minded respectfully putting my own food away when asked, had the red headed staff member not been so offensive in her attitude.

Won’t be returning. And have even noticed multiple trip advisor reviews highlighting the same particular red head staff member and her appalling conduct toward customers.

Having previously managed a team in the hospitality industry, I strongly advise this individual gets retrained on the way she conducts herself and speaks to paying customers. Even more so if she happens to be the owner of this establishment.

UPDATE, in response to Dimitris.

“You do not make excuses for your policy on food” yet you had no food available.

As stated above. I’d have respectfully put my own food away and initially did. But it then dawned on me how disgusting the manner in which your colleague spoke to a paying customer.

It’s laughable that you think I was abusive. I merely made your colleague aware that her conduct was abhorrent, entitled and rude.
Then she lied multiple times.
To which I just repeated myself more emphatically.

And you can distort the facts as much as you like. It was one and only one customer who, with no context of the situation whatsoever, decided to chime in asking me to leave it be.

And as for my partner, she merely didn’t want to risk my getting stressed as I have a heart condition.

But you carry on running your buisness as you do. The fact that there are numerous reviews both here and on Trip Advisor that flag the rude nature of staff at you establishment is proof enough that there something very wrong in what you consider acceptable customer service.

Great place to go. Nice atmosphere and great service! The coffe was very good and the gluten-free cake too. I definitely recommend it if you want a nice coffe in the Bay.

Really great coffee and hot chocolate - the Nitro Cold Brew is incredible and there's so many types of hot chocolate to choose from.

Pretty bad coffee. Temperature was tongue-burning, destroying the milk taste. Coffee taste is bland and shallow. I’d say even Costa serves better coffee, and that’s a very low bar.
