The cheese factor is high at this enormous shed in the barren blocks south of West Palm Beach International Airport, but come the weekend, it's lively as a Tegucigalpa marketplace... with a similar ethnic mix. The Central American immigrant families are in their finest, the men in Western gear, the women in brightly colored skirts and blouses, children in tow. They come for the trinkets, the kitchenware, the cut-rate clothing, the religious articles, and the company. Gringos head for the psychedelic shop, the magic store, and the anomalous traditional Italian deli, with a selection of wines, cheeses (including fresh mozzarella), meats, pastas, and other specialty imports to rival New York's Grand Street. For extra whimsy, drop $4 and take in a show at the Puppetry Arts Center of the Palm Beaches. Avoid the food stalls, where some items look as if they've been exhumed, then deep-fried.
