Place fish fillets in shallow baking dish. Combine soy sauce, lemon juice, garlic, ginger and Worcestershire sauce. Pour over fish and let marinate in the refrigerator for 2 hours or overnight; do not drain. Remove from refrigerator. Sprinkle with salt, pepper and cinnamon. Bake at 350 degrees for approximately 20 minutes, until fish flakes easily when tested with a fork.
Note: If baking dish is not temperature proof, bring to room temperature before placing in oven.
