At this time last year, Charles Clark was making an impressive name for himself as head chef at Tasca Kitchen and Wine Bar. These days Clark heads up the kitchen at the new downtown Elvia's, where he proves he is a master of many culinary disciplines. The killer bee menu includes grilled sea bass, cold avocado soup, portobello mushroom tacos and seviche. After dinner on the weekends, stick around for live Latin music and dancing. After midnight, the dance floor is as lively as the food.
