Cositas Ricas If you’re standing under a large, multicolored cow suspended over Roosevelt Avenue, you’ve come to the right place. It’s hard not to be in a good mood at this neon-lit, 24-hour Colombian diner in Jackson Heights, open since 2000. The hand-painted cartoon characters, peace signs, and Postobon bottle caps make an immediately warm impression. So does the service. The staff are eager to offer recommendations, which is highly appreciated, given that the extensive, photo-filled menu ranges from trout, to chicken fingers, to ham-and-cheese sandwiches.
