I think they still taste good but crikey they don't half look small now. My wife reckons they are much smaller than they used to be and refuses to believe we used to eat a bigger one called Magnifico so I was made up to find another post on this site confirming it wasn't just my imagination. The ordinary ones were still bigger than now and I found a fellow saddo who also frets over Cornetto sizes and found the original ad .....

FWIW - Any Cornetto fans reading this now (end Feb 2020)should get down to their local Asda as I went in last night to see if they had any chocolate type ice cream treats and saw they had Buy 5 for 5 on boxes of Cornetto Classic. I've no idea what they normally cost but 30 of them for a fiver seemed a good deal. If you do decide to invest make sure you take a bag because the Cornetto might be small but a box of 6 isn't and 5 icy slippy ones is near to the limit of what you can carry to the car.
