BONAZA COFFEE ROASTERY In terms of aesthetics, Bonanza wins in Berlin. Tucked behind factories, you are welcomed into a large minimal space: cement floors, white walls and plants everywhere. Glass cabinets filled with yummy scrolls and of course, the big list of coffees. Made with good taste and good style, Bonanza will make you feel trendy as soon as you walk in. There are two Bonanza Coffee locations in Berlin and we visited both.
