"What do you want to order?"
Translation:Що ви хочете замовити?
I am a native Ukrainian speaker. Usually we say "бажаєте", not "хочете" in such context. Okay, I can agree with "хочете", maybe it's casual to some dialects. However the program doesn't accept a synonym "бажаєте". That's a problem.
Also, the Lviv idiom is "Що то має бути?".
