The Box Donut near the Keleti Railway Station is slightly smaller than the unit by the Nyugati Railway Station, however, the high-quality is the same. The delicious doughnuts are generously packed with chocolate, poppy seed, and caramel, while their fillings are sometimes fruity, while other times are flavored with vanilla or Callebaut chocolate. We can wash the doughnuts down with a tasty coffee or lemonade here, which is a perfect way to kill some time while waiting for our train.
