I'm celebrating my graduation this Summer and my father will be flying in from Germany for the weekend. I'm looking for a restaurant with extraordinary food, but not excruciatingly formal, with an atmosphere conducive to conversation. My father loves good food and wine, and has an old-school "I don't eat seafood unless i can smell the ocean" attitude. Since Europe can't tell a good steak from a hole in the ground, I'm thinking steakhouse? Someone recommended Grill 23? Suggestions would be most appreciated.
