Have been here 3-4 times and it never disappoints.
I always usually go with the special or whatever the staff recommends that night, which has traditionally been steak. I have had a couple really well cooked steaks from The Capital Grille.
The prices are expensive and you can pretty much assume that you will be paying $100/person easy after drinks and an appetizer or desert. It is however very very good.
If you are in town do your self a favor and go grab a steak here.
