For coffee lovers out there, it doesn't get any better than Vida for fabulous real espresso and lovely Portuguese pastries. The Kloof Street location is frequented by model types - a bit pretentious but good for people watching.
Local chain - Kloof Street, city bowl, Waterfront.
Updates
There's also an outlet in the new terminal building at the airport, on the ground floor, before you go through security.
Is this your business?
