{ROTFLMAO} That's EXACTLY what they think it is... Steak with tartar sauce.
I was having lunch in Mövenpick with someone who ordered that, ...and after she ordered it, I asked her if she knew what it was, ...well she got all pissy and arrogant on me, so I just smiled and told her I hope she enjoys her meal. Who orders steak tartar well done except someone who doesn't know what it is? I almost busted a gut keeping the laughter in when it arrived. Her eyes nearly fell out of her head, ...but she was determined to put on a brave face, and not to give any of us the satisfaction... so she ate it anyway. That was the best part. Every so often, I'd enthusuastically asked her, how's your steak tartar? She'd say "It's wonderful" then take another bite. The poor thing almost turned green trying to finish it. When she excused herself to use the restroom, we had the waitor take her plate away figuring she had endured enough punishment. When she came back to the table, she had the absolute audacity to make a huge fuss that we had allowed the waitor to take her plate when she wasn't finished with it just yet. We had been there 2 hours, everyone else had long finished eating and she had barely taken 3 bites. Of course she was finished. Talk about looking a gift horse in the mouth! The waitor who had witnessed her hissy fit when we had ordered, as well as her stubborn refusal to admit she made a mistake, overheard this new complaint, and decided to have a little fun with her. He profusely apologized for taking the plate and insisted he would have the chef make up a fresh batch for her. Immediately an expression came across her face resembling stark raving terror! that's when we lost it... couldn't keep the laughter in after that.
ps - It took her 2 weeks to admit she thought it would be a steak with tartar sauce.
Lol. I've had exactly the same experience. I didn't bother mentioning that tartar sauce is usually only eaten with seafood, not steak.
I almost never see it on menus anywhere. Can you really still get it at Mövenpick today...?
