I have a layover at LHR airport for about 3 hours. I am craving a salt beef sandwich. I usually go to Selfridges for one when in London.
Would it be crazy or impossible to get to Selfridges and back in 3 hours? Or are there any other places which may be closer that I could get a salt beef sandwich?
If this is impossible, any other food treks nearby that can be done in a few hours? I am up for anything casual and British.
