What plant could this be?

[Blankscreen]

In my local town I keep walking past lovely really fragrant large bushes which are beautiful white flowers on them. They smell amazing.

I haven't taken a photo but does any one know what it could be?

Thanks

Jasmine?

at this time of year, probably choisya, aka Mexican Orange Blossom
