Some background: this trip was originally my 40th birthday present from my now ex-wife. We've since divorced and I'm insistent on going by myself, as something always seems to come up and ruin my overseas travel plans. So, I want to treat this as a sort of growth/healing/looking forward trip.

About me: I've traveled quite a bit but I've never been outside of North America. Europe is completely new to me. I am very fond of football, food, beer, hiking, history, and new experiences. I prefer to stay away from tourist traps and I'd rather find hole in the wall type places that are recommended to me by locals. When I travel somewhere, I want to immerse myself.

I'll be there for ~9 days and I have the first 5 days fully worked out. What I need help with is figuring out what I want to do in London for the last 3 days of the trip before I head back to the airport. Other than going to a Fulham game next Saturday, I'm completely wide open. I would prefer to stay in the greater London area since the first half of the trip already involves quite a bit of travel.

I'd love to hear your recommendations do's/don'ts, or general guidance. I'm open to pretty much anything.
