Neither. I always get one of their more seasonal offerings. You can get a steak at any signature, and I think it's always the least exciting thing on the menu.
Last time I had Seared Snapper with Fig Risotto, Forest Mushrooms and Pinot Noir Reduction. Another time I had Ostrich Filet with Sweet Potato Gnocchi, Wild Mushrooms, and some sort of berry sauce, just to name a couple.
The steak is good though. Not outstanding, but a good steak if it's what you're craving.
