Arrggg. College Cafe Steak!!! THIS is why I don't eat out.
Yes, recommend this marinade to the chef. I was just giving the shorthand version. My secret recipe marinade contains 4 types of vineger, two of which j prepare personally. A few other spices, for flavor, and Apple or orange juice. Slow cook on my kettle grill. Mmmm.
Unless you're at a 5 Star restaurant that serves aged beef, I recommend stick with the hamburger.
