It's been a long journey pushing westward in the brutal traffic. But here you are at the roadside oasis called Rancho los Cocos. This glorified country produce stand used to be really way out west but is now in scenic Westchester. Wooden tables piled with locally grown fruits and vegetables are lined up under a wide roof, which also shades a cluster of little tables and chairs. Here the weary commuter can enjoy Cuban home cooking chosen from an indoor minicafeteria. Or try a shrimp, beef, or chicken shish kebab grilled to order outside. Then there's the wonderful los Cocos juice bar offering a full complement of fresh juices and batidos. When you're finished eating, browse through the produce and bring home a bag or two of whatever's in season.
