Looking for VERY good dry cleaner

I need to get my gown dry-cleaned before my fittings. It was a sample, and while there are no stains it does need to be 'freshened up'. My bridal salon has written in to the contract that I can take the dress and bring it back for my fittings, but I have NO idea where to take it.

Does anyone know a good drycleaner they can recommend, prefereably one that has worked with silk organza??

Thanks, -Meghan
