Why it ships alone
Fish keeps its own company.
Raw fish is the most fragile thing we sell and the least forgiving of a warm hour. It is packed in its own box, in a thermal pouch with ice packs, and goes out on an overnight service so it is with you the day after it was cut.
It never shares a parcel with meat, and it never shares one with the food hall. That is a food safety rule before it is a quality one.
Caviar goes further still and travels entirely on its own, even when there is fish in the same order.
