Answer :

In the name of Allah, Most Gracious, Most Merciful

Assalaamu `alaykum waRahmatullahi Wabarakatuh
 
If coupons are given by the vendor with the meal, it will be permissible to accept a prize from them as they are given to the customer on a voluntary basis. It is important to remember that it will only be permissible to accept a prize which is allowed in Shari’ah.
And Allah knows best
Wassalaamu `alaykum
