5th Avenue Chocolatiere’s top seller is their truffle. It’s so popular in Japanese guide books that the store specifically provides the description of this specialty in Japanese. And no wonder these truffles sell like hot cakes, they taste like butter… chocolate-covered butter. And they melt in your mouth like butter, too. When left at room temperature, they only last for two to three days, (as if you wouldn’t be able to finish them in two to three days!) but they are also delicious frozen. A small box of eight decadent truffles is $15 and well worth it.
