It can be very hard. I believe GB requires permanent residence of US. I did it once when I was on F-1 but it was business related and we had invitations from a few large corporations such as HSBC. And yet I still got interviewed at the Heathorow airport.
Also, how does your friend plan to get a US visa in UK? If your friend has a valid entry on the visa then it's worth a try.
