Very doubtful its something from a bottle, though probably something you can come close to finding or recreating if you know what the sauce was called. Looking at the menu I see 3 options toss those in google and I bet you can find a recipe.
Prime Rib-Eye Steak - Whole-Grain Mustard Sauce
New York Strip Steak - Chimichurri
Filet Mignon - Truffle-Butter Sauce
