Londoners, are you a regular Theatre goer & which is your favourite Theatre...?

I love the theatre, but I work as a stage manager so I am a bit biased. I forget how beautiful the bits the audience see are. Backstage they aren't half as glamourous! Most dressing rooms are small and sometimes windowless and plain and when there is an explosion in the population, it is not unknown to be sharing the space with a number of small furry creatures. It isn't often I get the chance to go out front and see all of the beautiful decoration. I don't really have a favourite - it is usually the theatre I am working in at the time! I worked at the Apollo last year and I can't honestly remember what it was like front of house, but the staff are lovely.
