I've had it and thought it was delicious. Taste is so subjective so it's hard to say whether you'll think it'll taste like an American steak. I don't think it tastes like one you'd make on your own grill. On the other hand, it is not overly exotic in its flavor. One thing I've noticed at many restaurants throughout Disney is that they tend keep things somewhat "American" but with subtle influences from the country the food is representing.
You can get it prepared however you'd like. One thing that I can say about my personal experiences at Sanaa is that they waitstaff is very knowledgable about the menu. They are great at making recommendations based on your palette and preferences. Discuss your taste preferences with your server and I'm sure he or she will be able to find a dish that accommodates your preferences or will have the chef modify a dish so that it does.
Last time I had this dish it was paired with Post House Penny Black. Great pairing and I definitely recommend it (If you're a wine drinker).
