Great Sunday-only market with about 500 vendors. I was looking for a UK currency hair dryer to bring with me, since some hotels don’t have them. I got one for £6.99, and they also had socks at excellent prices. Lots of utensils, work gloves, and things like that. They have a number of food places and lots of picnic tables to sit at and eat. It opens at 9am, and you have to get there early, because it was getting very crowded by about 1pm.
Hours are Sundays from 9am-3pm. Take the tube to Wembley Park Station, Jubilee, or Metropolitan line. The day we went, the station was closed, but things were well-marked, and they had buses from Baker Street.
