Certainly looks like a Cherry Tree to me. The only thing that may concern me is the location, being on a carpark the Cherries may be coated / or have absorbed (not sure whether Cherries do or not) pollution from the vehicle exhausts. I always try to pick fruit away from traffic when possible.

Stu,
He lives in London, I think everything around there has absorbed a fair bit of pollution
Know what you mean though. Tastes much better from the countryside
