Best dating location & activities to do in patna on first date.

My girlfriend is living in patna & we have been texting & video calling since last 2 months. This will be the first time that we would be meeting & I have never been to patna or even Bihar. I have no idea about that place. So, suggest some good dating location & activities to do in patna that can make bond between us stronger. We will get hardly one day together.
