On holidays here from Aus and I was super excited to taste the coffee here and I wasn’t disappointed. Lovely and smooth coffee with cocoa notes to finish. Atmosphere was great and enjoyed the sweets as well. Lovely staff and we will definitely return!

Coffee wasn’t that great. Ordered a cortado too and was the same as my husbands latte..Not sure if it was because we’d just had amazing coffee at ‘Plan’ or other reason. Service wasn’t bad, but not great either. Atmosphere was ok. Few tasty looking snacks and things too, but only tried the coffee.

Friendly welcome followed by great coffee and a cheeky cannelloni to go with it. Nice relaxed atmosphere with a good selection of hot and cold coffee.

Run by two dedicated coffee lovers from Italy, Quantum Coffee Roasters serve quality and keep challenging themselves with looking for the better. I'm lucky enough to be living next door and whitnessing their journey. Best coffee in the Bay with one of the best Flat Whites in Cardiff.
