Here's something refreshingly different: a restaurant that's cooperatively owned by the chefs, servers, and managers, and some of their friends. (Its full name is "Taco Pica Worker Cooperative Restaurant.") It's bright, festive, and just a short stroll off King Street. The restaurant developed a devoted local following when it opened in the mid-'90s, thanks to a menu that's a notch above the usual staid local adaptations of Latin American and Mexican fare. Reliable dishes prepared here by the Guatemalan staff include pepian (a spicy beef stew with chayote); garlic shrimp; and shrimp tacos with potatoes, peppers, and cheese. Vegetarian items are also available, as are a good variety of fresh juices and libations -- fruit margaritas definitely put out the fire in a hot dish. Insiders' tip: There's sometimes a live guitarist at night, and the place even occasionally turns into an impromptu Latin-flavored dance club on weekend nights (after the dinner service, of course).
