I've been going to Giorgio's for about 3 years. Best salon in Kew Garden's, in my experience. All the 5 hair cutters I've used did very good work. Janet, in particular, is an artist, and tries little variations each time (with my permission, of course). They always come out fantastic. The entire staff has been friendly an daccomodating.
Pros: Ambience, Friendly, Not expensive, great cuts
Cons: Honestly, none
