Don't do is let the steaks get to room temp, the other thing people mess up is they under season. Use a good amount of salt and pepper until you think it's adequate and them add a little more. Don't over cook. Get them to Med rare temp ( use a digital thermostat if you have to). On high heat. Pull them off the grill and let them rest. The other thing is that you've worked hard to develop a nice crust in the exterior if you let them rest on a normal plate with a foul tent over top they will go soggy.
Place the steaks on a cookie rack onthe counter so they don't sit in their own juices and get soggy. Last thing... Use a warm plate to serve your steak on, you don't want a cold plate to draw the heat out of he steak.
