All around, snaking between clusters of booths, runs a conveyor belt of segmented crescents. It bustles along, carrying colourful plates of every kind of sushi imaginable. There are bowls of seaweed salad with chilli flakes on top, and faux sandwiches with pressed rice for bread and crab meat inside. Interspersed between tender looking sashimi and rolls dotted with roe are the most glorious pieces of cake. Their lofty icing fills their plates.
