A young couple travel to a chinese restaurant; little do they know that an encounter with a coven of witches is on tonights menu.

Good premise, but you don't tell us what the main characters must do. What are their actions when they find out that the witches are at the restaurant?

This one is too vague IMO. So the story is about their travels to the restaurant? Or what happens inside? Or do the witches curse them?
