They are at 31 Bond Street, Ealing, W5 5AS. Turn left out of Ealing Broadway tube (Central Line); right at the T-junction and third on the left is Bond Street. Ten minutes' walk.
The man in charge there is Vinod Bedi on 8579-3389. No Strollers discounts available, sadly, but they do have probably the best range of kit in London.
