I used Crystal Clean Drycleaners, 89 Tower Bridge Road
(green sign, just near the junction with Decima St/Bermondsey St) last year to alter a dress with an unusual neckline/straps and they were absolutely lovely and I was really happy with the result - and price. I advise ringing up first if it's out of your way to check when the tailor will be there so that they can see it on you and know exactly what to do.
Also, we use the dry cleaners in The Circle on Queen Elizabeth St very regularly for cleaning and minor alterations/mending and they are really good (and honest, deducting the cost from the cleaning of money we didn't realise had been left in a pocket). They just unpicked some darts in a shirt that the shop tailor had done too tightly and they have done a fab job; no trace of the darts ever being there!
Hope this helps :)
