London Market

I recommend Greenwich Market over Camden Market. Camden Market is like Harajuku in Japan. They sell all the same souvenirs. There is a long-standing fish and shops nearby, but you can eat anywhere you like. Greenwich Market is on the way to the Royal Observatory Greenwich. It is held near the nearest station to the Royal Observatory Greenwich, but I think it has a more London feel to it than Camden. It's a place that locals seem to go to.
