While I was in New York I went to Jacques Torres's chocolate shop (66 Water St., Dumbo, Brooklyn; the directions in the link below are very good) twice. The first time I had hot chocolate and a pain au chocolat; the second time, wicked (spicy) hot chocolate and a croissant.
The pastries were excellent. The chocolate, especially the classic hot chocolate, were easily the best I've ever had. Intensely chocolately, rich, and thick. I also bought chocolates, peanut brittle (excellent) and hot chocolate mix. The chocolates are very good and, given the quality, considerably less expensive than Manhattan's best. $40 a pound versus about $60 a pound a La Maison du Chocolat. Sometimes you luck out and can get "off-the-menu" flavors. When I bought mine, I got some cardamom, an overrun from a special order.
The place is small. For those who don't want chocolate to go, there are only two small tables. On my first visit I was prepared to sit in the window when a woman sitting alone at one of the tables invited me to join her. We chatted a bit, I mentioned how I had found out about the shop (chowhound) and she said she's a chowhound contributor too! Once again ... New York ... not a big city ... just a whole lot of small towns really close together.
