How to express discount properly?
I work in a cafe and I'd like to know if I translate the menu properly. Can someone help me ckeck it?
"Other drinks for $70 off"
One meal served with salad and one drink. If you choose a drink in the set, it's free; if you choose a drink which is $140, then you can get the drink for $70.
Is there a better way to show it on the menu? Thanks in advance!
