The view from Waterloo Bridge at sunset does it for me, on a good day it looks very beautiful. So good the Kinks wrote a song about it: Waterloo Sunset.
Wordsworth had similar views about Westminster Bridge
520. Upon Westminster Bridge
EARTH has not anything to show more fair:
Dull would he be of soul who could pass by
A sight so touching in its majesty:
This City now doth like a garment wear
The beauty of the morning; silent, bare, 5
Ships, towers, domes, theatres, and temples lie
Open unto the fields, and to the sky;
All bright and glittering in the smokeless air.
Never did sun more beautifully steep
In his first splendour valley, rock, or hill; 10
Ne'er saw I, never felt, a calm so deep!
The river glideth at his own sweet will:
Dear God! the very houses seem asleep;
And all that mighty heart is lying still!
