Pick your favorite kind of steak and order it....my guess is it will be good. When I get to go to a place like that (Ruth,Daniels,Metropolitan,El Goucho,etc) I usually order something I don't cook at home. Step out of the box so to say and discover something new (if that is possible with cow!).
I think it's impossible to get a bad meal at a high end steak house.

On that note who has been to the Wolf Lodge off I-90 in Idaho near CDA? That place is a must if you are traveling through the area during dinner time. Make sure you have reservations. The antlers and other old west stuff on the walls is almost as good as the food. They cook the meat in an indoor bbq in front of all the guests in the middle of the place. Very good.
