Just had one for afternoon tea.

If you ever had vegetarian burger... it taste similar. Some might mistake it for Chicken.

Others... the really picky people will say... the origin of "China cardboard patty" have similarities.

That said " Approved" 99% people eat to live. We gotta accept that in future "Lab grown meat" is the only ethical way ... and religious reasoning... not killing animals ect ect.

Kfc will push it if, it feeds their profit better. Otherwise it is tough trying to beat the poultry industry.
