If you are coming by Underground (Central Line), turn left coming out from Marble Arch station, and then immediately left again, along Old Quebec Street. This is a short road, and at the end you will see New Quebec Street facing you. We are nearly at the end, on the right. The walk takes two minutes.

If you come by car, there are several large car parks nearby, as shown on the map. You can stop very briefly outside the shop, but it's risky!
