Oh very interesting, as for me it is the complete opposite: I grew up only knowing real truffle and am now in a position where the fake stuff is just too intense for me, which is kinda sad as some "higher class" restaurants happily combine the two, to get you the look (eg by grating in front of you) and the taste (via some oil in the sauce)

I'd be very grateful if they started labelling it accordingly as they do it with other synthetic flavours (eg strawberry, GER)
