I posted this in response to a question on the Cravings Board, but I think it belongs here. I write about this because it is one of my favorite haunts and because I once interviewed the owner Coco for a local newsletter article so I got the history and all.
La Nueva Bakery (not to be confused with Café La Nueva Bakery they will soon open on 37th Ave & 85th St) is owned by Armenian Uruguayans but also has some very good Colombian bakers. They have good buñuelos and pan de bono and other Colombian pastries. They also have lots of great Argentine and Uruguayan goodies. The tiny pastries and cakes are quite sweet, featuring lots of dulce de leche (carmelized milk which has lots of other regional names). They're cute to take to serve to company or take to people's houses but make sure they're fresh. Try some of the other fatturas, like vigilantes con o sin crema. They're not all super sweet and contain all sorts of different fillings. They also have quite a selection of breads. The empanadas de pollo and carne are good, but they have empanadas mendocinas (meat with raisins) and fried cheese empanadas that are great. The sandwiches de miga on Wonder-type bread with different fillings are good, but I personally like the sandwich de milanesa, either veal or chicken. They have good coffee and a pleasant area (by local standards) to wile away some time with friends or simply a cup of coffee, especially if there's a soccer game on the TV. There are changing specials, espcially for the holidays, a large selection of sodas and juices and lots of good frozen pastas, like ravioli as well as yerba mate and other cans and jars from the area. Also available is chajas, something i have only eaten here and in El Chivito d'Oro, owned by the brother of Coco, owner (with his wife) of La Nueva. It consists of a light cake, with dulce de leche and an apricot half inside, all coated in whipped cream and strange-looking meringue lumps. It's very sweet but quite good.
This family also founded and then sold the now-apparently-defunct chain of La Uruguaya bakeries which were wonderful but smaller. They had an Uruguayan pizzeria for awhile and still
