Iberia Airlines Iberia Plus - IB DUS-MAD..... Food/Drinks???

I am booked DUS-MAD on Iberia/operated by Air Nostrum and read differnet things about food/drinks on board.

I either read that there is no free food/drinks served or that there is something close to a business class serving even in Y (thats what is booked) when flights are operated by Air Nostrum.....

So... What is right????

Any help appreciated, first time on IB

IB mainline food and drinks for sale on European flights. Don't know Nostrum, though.
