This may sound a little weird but here's the thing...
My fiancee and I went to Shula's steak house in the Dolphin to celebrate our engagement.. as we saw the foot ball pictures all over this classy steakhouse, it slowly sunk in that it was Don Shula's resturaunt. If he is in to football, he will love the fact that you took him there. If you're not into football its ok too, basically as football as it gets is that the menu is printed on a football and there are some painings related to football on the walls. It's not a sportsbar. It's an honest to goodness steak house, candle lit tables, excellent champaign and wine, great food.
We gave a gift certificate to a couple that were going to WDW on their honeymoon, and they loved it! The guy was thrilled about the football and the girl loved the food and wine.
It's a tad expensive, but really nice.
