Bars? Nightclubs? .......... ummm ok.
My most romantic date ever, was my fiance, taking me to a spot in the desert, in Ajman's desert. It's a spot he knows well, deep and probably close to Oman.
He had a small Arabian tent set up. A small fire in the front. and me and him, with the pure winds of the desert.
That dwarfs anything I've been exposed to in Europe (hey you look like a nice bird! wanna have a beer!!) .

Take her/him to the desert. It's a liberating experience. Everything ceases to exist, just you and him/her. And that's all that matters.
