Antiquing in Islington
Here it is another antiques market in London which is worth to visit: Camden Passage. Just a two minutes stroll from Angel (northern line) tube station, you will find a selection of stalls in an open air market. The market is open every Wednesdays and Saturdays.
I went there on two Saturdays and I would say this place is a little gem. And it suits my budget. I can say that you will be happy coming back home not empty handed.
There is also Pierrepont arcade with a selection of antique shops. Some of the shops, I believe, open more regularly than the market.
And interestingly there are more (and bigger) antique shops if you stroll along the alley.
