Poor quality and expensive. Don't use.
I would not recommend this dry cleaners. I asked them to dry clean my suit and fix a pocket. The suit wasn't cleaned very well (still had some light marks on) and the pocket hadn't been repaired. I didn't get a refund.
There are lots of other dry cleaners in the city of London that you can use.
City Slickers is a dry cleaners that also offers an ironing service. They also clean suede garments. In addition a repair and alteration service is provided.
