Richly furnished and decidedly grown-up, Preston’s serves a deluxe menu with items as compelling as sweet, jalapeno-glazed black cod and a daily wild game selection. Menu icons indicate “super food” items that are “rich in antioxidants, fiber and/or vitamins are especially health-promoting and disease-preventing. Among these are avocados, citrus, spinach, whole grains, salmon, sweet potatoes, garlic, onions, tomatoes, berries and nuts.”
