Gothamist and Serious Eats had a wonderful piece on amazing dining in Harlem.
East Harlem’s very own Super Nice cafe was deservedly mentioned:

There are lots of great treats to be found in Harlem, whether for breakfast, afternoon snack, or dinner dessert, but the best doughnuts in this part of town right now definitely come out of the kitchen at Dan Cohen’s superb coffee counter and bakery, Super Nice. Cohen first got our attention more than a decade ago with his Danny Macaroons booth at Smorgasburg, but Super Nice shows that the man is way more than a one-trick baker. The fat, yeasty doughnuts, glazed up and often studded with crisp goodies like Fruity Pebbles, are stellar (and happen to be vegan), and the dense cake doughnuts, scones, cinnamon rolls, and croissants (and croissant sandwiches) are all equally delicious. Breakfast in bed never tasted so sweet
Supernice is located at 156 East 117th Street (917-261-5069) – Order Now
