New York has its share of upscale java joints, but none that specialize in Indonesian brews. Enter this Greenwich Village café, a narrow 70-seat spot pulling blends from the island nation with a sleek siphon brewing system. The coffeemaker on steroids—called the Alpha Dominche Steampunk—uses a steam-powered boiler to crank out four sharp cups of joe at a turn. Signature drinks include es alpukat (coffee avocado milk shake) and a sweet brûléed cappuccino, both made with organic, single-origin beans. Wood carvings salvaged from Java and Bali hang on exposed-brick walls—a decorative nod to the owner's tropical birthplace—and an inverted iron chandelier dangles above the 1,500-square-foot room. The pastry selection skews American—croissants, turnovers and Danishes—but lunch plates are all Indonesian: satay maranggi (coriander-spiced beef skewers), soto ayam banjar (a lemongrass-and-ginger chicken soup) and nasi uduk betawi (rice and beef stewed in coconut milk).
