Fat Crab is a restaurant in London that serves seafood boils with lobster and king crab. The seafood, rice, and sauce come in a bag and are eaten at a medium spice level, with french fries on the side. On Christmas Eve at 8 p.m., only guests with reservations could dine in, while walk-in guests could order takeout only. The king crab legs are sometimes served thin, so the portion can feel small.
