An independent roastery not too far from the Principality Stadium, Uncommon Ground is the place to go in Cardiff if you are extremely serious about your coffee. Don’t take that to mean that the atmosphere is pretentious — far from it, this is a laid-back cafe that knows what it is doing when it comes to hot beans. They prove that this isn’t rocket science, and simple care and passion can go a long way when it comes to a good cup of coffee.
