Sure thing! To get to Brent Cross Shopping Centre by Tube, you’ll want to take the Northern Line. The closest station is Brent Cross, and it’s only about a 10-15 minute walk from there to the shopping centre. Once you get out of the station, just follow the signs, and you’ll be there in no time.
If you’re coming from central London, just hop on a northbound Northern Line train heading towards Edgware. No need to worry about transfers if you’re on the right branch. If you’re unsure, just make sure the train is heading towards Edgware, not High Barnet.
Hope that helps!
