Dating A Foreigner girl in Khobar? Help

it is risky to take her out to a public place. if there is some private function, then you will be able.

So Coral Island is a big no?

Go across the border to Bahrain, to be on the safer side

Hello Maythan,

Taking a lady by road to Bahrain who is not legally related to you is a project in itself .

The other options is to go to Bahrain by air which could be expensive but just a moment:

As long as both of you are dressed in "similar cultures" and act normally ie you dressed as an Arab and the lady in Abaya, I do not see any problem in taking your female friend to public places. I have never heard of the religious police stopping couples  at random and asking for marriage certificates

I will be careful not to stop by at the corniche in deserted spots irrespective of how tempting and safe it may appear.

Unfortunately i don't have a private place

I would but it's too much. Customs both ways isn't fun lol.

you can get in to a bus which is going from dammam or khobar to Bahrian.

This isn't an issue. It's like getting on a plane. You won't have any problems.
