I went back to Dulce yesterday (in the Maerua Mall, Windhoek), truly looking forward to another good espresso.
Alas. It was not to be. I ordered the espresso, and out it came. But it looked nothing like what I was expecting. In fact, it looked like everything I would have expected from your average African cafe/restaurant serving coffee (mind you, not that the coffee in many Asian or even European countries is any better). A sad, over extracted, watery, thin, muddy drink - they should have switched off the water flow at least 5 seconds earlier and perhaps it would have been good.
That's the other problem you seem to get in many African restaurants or cafes - consistency is lacking.
I couldn't even bring myself to take a photo. *sigh*
