Place steaks in a resealable plastic bag or dish with high sides just large enough to hold them. In a small bowl, stir soy with brown sugar, sherry, vinegar, oil and garlic. Pour over steaks. Seal bag or cover dish. Refrigerate fish for 4 hours, or meat overnight. Turn bag or steaks in dish once during marinating.
When ready to cook, preheat barbecue and oil grill. Lift steaks out of marinade. Pour marinade into a small saucepan. Bring to a full rolling boil in a pan set over medium-high heat. Then remove from heat while grilling steaks. Grill steaks for 6 to 8 minutes per side. Serve right away with sauce.
