Japan is the only place to eat steak tartare. The Kobe beef is perfect for it. However it is expensive (from USD 200 to USD 500 depending on the restaurant). In the US I would only make it at home and not trust any restaurant to get this right, IMHO. Actually a good carpaccio is often more satisfying and has more of the "essence of beef" flavour, but that is equally hard to find. This kind of food is simply not available in Orlando, the closest would be the restaurant at The Atlantic in FLL (which is ex-NYC).
