I like this coffee shop. Good place to get on with work, excellent level of service with simple food and tasty coffee delivered fast and friendly.
Nice coffee house and good coffee. Nice staff too.
Quantum is my go-to out of all the coffee shops in Cardiff. The staff are warm, friendly, and knowledgable, and you never feel like you’re intruding if you stay there for a while! The coffee is the best in the capital, and the cakes and warm food is just lush. Lovely atmosphere, and I love the decor - including the information about the old docks. Would highly recommend!
Good food, great location
Great, friendly staff and great selection of specialty coffees.
Cool quirky coffee beer
Great location in Cardiff Bay with funky decor and good range of drinks.
When we entered and made it clear we'd got a wriggle offer the guy serving wasn't very clear as in mostly nods and incomplete sentences
