I <3 Aldgate East
I guess your local tube station will always be a favourite because you associate it with being home. I particularly like Aldgate East because it's all scuzzy and mid-refurb, I say 'mid-refurb' but it's been in its disheveled state for the 2+ years I've lived here. Unusually, there are no escalators at this station which is a plus for me as I have a fear of falling down them. I hope they never finish the refurbishment. Knowing TFL, they probably never will.
