Shameless plug, but I were able to do such thing at the Wimbledon Evans.
However, I think Brixton Cycles is pretty women-friendly (as a couple of them do work there), Nhatt! left BC sadly, but they should still be able to help.
This is AFAIK, being a bloke I have no idea how the other bicycle shop may treat the women, Condor Cycles is quite good mind.
