As a tourist, I found it certainly worth a visit, if only to see the old bells from St Martins in the Field. I well remember the old nursery rhyme "Oranges and Lemons" where "You owe me five farthings," say the bells of St Martins. I fluked a bell ringing lesson from a volunteer. It was quite an experience.
I wasn't impressed with the deveopment along that part of the Swan. Be warned, Nature will have its way.
