Best boxing gyms/scenes in England...

What are the best gyms or boxingscene in england? Also what era was there peak at??? I use to live in london in 1995-97 but never paid attention because I was to young to know anything about the boxing game other then naseem hamed. I remember my uncle was stuck babysitting me and he would take me to gyms around town, he himself didnt box he was just kinda like show up and watch the practices since there wasent really internet in the mid-90s that coverd boxing like now a days. Basicly he was like a hardcore fan and I dont know I guess thats how they followed boxing, by going gyms around the town I suppose.
