The Cowboy Ribeye is 22 ounces with bone-in. And some math:

  1 gram = 4 calories
  1 oz = 28.35 grams
  -----------------
  22 * 28.35 * 4 = 2495 calories (assuming pure protein)

That of course assumes that the whole thing is pure protein, when it obviously has fat and bone in it. So at 1650 calories, the steak would have to about 2/3 protein. This matches up with my experience at Ruth's Chris. On top of that, is the delicious butter they serve everything in, which is additional calories.

So yeah, 1650 seems completely reasonable for the Cowboy Ribeye.
