I've had issues doing this before in France and Italy.
You can ask, but most likely not.
In France it was related to prep work that had to be done for the item.
It was a puff pastry crab dish they used to have, I never did get to try that.
If they have the steaks there then they may do it for you.
In Italy they were very strict (Alfredo's -these guys always had a bad attitude).
Great food though.
It was only 35 minutes before dinner (walk up not an ADR) and they would not let me order from the Dinner menu.
So everyone at my table ordered and I just ordered a drink.
35 minutes later I asked for the Dinner menu and ordered what I wanted.
Totally Ridiculous.
(Also I would keep trying for an ADR at a better time. France usually isn't all that hard to get)
