Guillam Coffee House – South Kensington

Walk into Guillam on a South Ken morning and you'll clock the serious coffee operation straightaway—the kind of place where they're not mucking about with pre-ground beans and milk foam art. You're looking at specialty coffee done right, the sort that pulls in locals who actually care about extraction times and origin stories. It's the antidote to the chain cafés that cluster around the V&A, tucked away on Gloucester Road where you can actually have a conversation without shouting over an espresso machine.
