I've known Oswaldz for some years now, and I love and hate it at the same time. The coffee is good, but several things are quite unacceptable. Most importantly, they will always safe shots from a previous drink and, if you are unlucky, they will just serve you this; who knows how long it has been sitting and oxidising there. For a place that boasts about being experts on espresso this is quite disappointing considering how much you pay for it—which I would be willing to if the drink was freshly made! The other aspect that adds to the disappointment is that a few of the baristas working there are lovely, but most of them are quite condescending and it seems like they are sparing your life every time you order anything.
