"Spring Cafe near Chinatown serves an ube sandwich with a slightly sweet flavor. The place is bright white inside with big picture windows that provide a bustling panorama of the commercial scene outside, very Olde New York. Seating is minimal but adequate, and sandwiches, burgers, salads, and bao dominate the menu. The ube sandwich ($5.95) comes on toasted multigrain bread with a thick layer of coarsely pureed purple yam, dried cranberries for tartness, and pumpkin seeds for crunch. It's classified as a breakfast sandwich, though one can get it for lunch." - Robert Sietsema
