If I don't know her well then I don't do dinner on the first time... She could turn out to be the most annoying chick then you are stuck there the whole time.
Often in short approaches I say "listen we can go for a coffee and after 10 minutes we will know if we like each other and want to hang out longer." You can say this in a light tone.
In your case I would just say that you are busy that night but can meet her for a drink at a local bar a bit later.
