Call it a novelty shop for foodies. Negotiating Cardullo's riotous aisles, you'll encounter chai truffles and white chocolate ants; cans of spotted dick and jars of cassoulet; pecan vinegar and piña colada jam; wines from Cape Cod and caviar from the Mississippi River. You can score some fine sandwiches from the deli counter too. Brits abroad will find storecupboard standbys such as McVitie's biscuits and Marmite - at a price.
