Currency to be used in Bahrain

You can use them everywhere, certainly have never been refused.  Occasionally, they will try to charge you for exchange rate but not often.

You can't use Dinars in Saudi though.

You can use Saudi Riyals everywhere in Bahrain.

10 Saudi riyals = 1 Bahraini Dinar.

Do keep in mind, some shops and outlets do not accept denominations lower than 10 riyals.

I've never been refused to use Saudi Riyals in Bahrain. If you want to exchange Riyals to Dinars, I would use BFC which is located across number of malls and the airport in Bahrain. Based on my experience, they offer the best exchange rate for many currencies. Some places also do accept other GCC currencies such as UAE Dirhams.
