The Portobello Market is for you if you like trinkets, endless displays of watches and rings, and little funky knick-knacks. It's a fun but crowded walk up and down the street in a charming neighborhood in London. Knick-knacks are not my thing, but I enjoyed looking at all the bright arrays of colors amongst shiny things. It's worth going at least once, and if you are really into trinkets, you could make a day of it.
