Design isn't important here. The place lives from its oversized windows, the pleasant wooden floor and the minimalist bar. If you can find a place at a table in the window niches, you'll have a bit more peace and quiet, and won't be sitting in the midst of the throng.
The breakfast is delicious, as are the uncomplicated lunch menus, and sandwich variations in the evening. You could say that the Propeller is a recommendation at any time of day. Even if you just drop by in the evening for a drink or cocktail at the bar. You'll always find yourself a spot.
