Of course we couldn't go to Fat Cow and not have any... cow. We had its infamous Fat Cow Donburi set lunch ($39++) - slices of charcoal-grilled wagyu beef with onsen egg and shiro negi.
If you observe during lunch, this is pretty much what everyone is ordering. We were there early and saw the chefs prepping tens of beef filets on the grill for their lunch service.
We and the chef recommend that you order your meat medium-rare so you can bite into the juicy egg-coated wagyu beef slices... Oh yes.
