Walk purposefully without intent scanning your surroundings. Let your brain naturally process incoming images. You're not blind to anything, seeing everything. Great food finds are made this way. Then when purposefully trying to find your serendipitous discovery again, is it hidden?
This was my Patisserie Orientale experience in Brussels. Found it by accident Saturday, tried to find it Sunday and couldn't, gave up and then rediscovered it.
Patisserie Orientale is located near the Grand Palace at #19 Rue du Marche-Aux-Herbes GrasMarkt. Prices are €2.50 per 100 grams.
