If you're looking to break out of London's tourist rut, I definitely recommend taking a tour with Matthew. We took what he now may be calling The Javelin Tour, which combines lots of street food with a trek through more of East London, ending at a hip "pub" on a canal near the Olympic Village. The food vendors he picked were amazing - from Thai to American bbq (beware the Holy Mother of God sauce) to the good old British Scotch Egg (tasty!). Our 6-hour walk took us through Clerkenwell, along the East London canals and into Hackney Wick - very cool all. This is a great tour for all ages, but college students or travelers in their 20s and 30s may find it a helpful overview for places to hit later on their own, during the day or in the evening. I know our kids (ages 18 & 20) wish we had taken the tour first thing in the week; it was a great introduction to the city and hit so many insider spots. Plus, Matthew is a relaxed, knowledgable guy to spend the day with. A top highlight of our trip.
