Sorry, I may have over-reacted to that video - I know that Doris is a kind, gentle person who wouldn't put up with abusive people so maybe the wrong impression was given (but I'm still not mad about the show!)
Covent Garden is what locals think of as a 'trendy' area, mostly for visitors and tourists. I'm sounding like an old stick-in-the-mud but I preferred it when it was the 'real' Covent Garden - that place that was recreated for "My Fair Lady" where Audrey Hepburn/Eliza Doolittle sold flowers. It did really look like that. There weren't any sidewalk cafes and fancy eating places then - just a few greasy cafes and a pub that opened about 5am or earlier for the workers who were finishing their shifts. You could buy all kinds of fruit and veg very cheaply and get hots cups of tea and buns all night. I used to go there with my hippie friend (you could get other stuff there as well!

) it was somewhere warm, interesting and very cheap.
Watching the news a few days ago, there was a piece about Coney Island being redeveloped and some of the locals were saying they were worried about what the developers were going to do and if they would spoil it - well, Covent Garden is a bit like that. But great for tourists!
