How do i reheat a steak?

I had two steaks last night a tony roma's and I took one home with me and left in in the fridge overnight. How do i heat it to get the most flavour out of it? Should i microwave it or put it on an electronic grill or just use a regular frying pan?

I often use the microwave, but I brush it with a little butter or olive oil. Remember that it will be more done than what you ordered at the restaurant. I only put it in for 30 sec at a time, that way I check it frequently so it doesn't get too dried out.
