That's nothing new, had it in Portugal years ago. My little brother loved it. I think it's pretty gross though.
Defo it had even reached the backwoods of Portlaoise where I was even served in such a way at my 21st in Portlaoise (which is tragically too long ago).
I'm in two minds about it myself. I do sort of feel like 'I'm paying you to cook my food' but also I did like the ability to have it 'my way' in different ways throughout the meal.
