DelRey is one of those great names closely linked to chocolate and pastry in Belgium. Its headquarters in Antwerp is a true temple that worships chocolate and from which it has been able to expand to other distant ports, with special fortune in Japan.

DelRey is facing a new renewal, with the challenge of attracting a local public to come more frequently to his establishment, while the arrival of tourists has not yet fully recovered. Their next objective is to develop a range of fresh viennoiserie with the same criteria of quality and style as their bonbons and cakes, although this seems to be a future challenge that will fall into the hands of Jan Proot, the fourth generation to take over the helm. In so good #26 we have the chance to enjoy of some of their signature cakes, like this Espresso cake which combines coffee and dark chocolate.
