Apple Market Covent Garden
Apple Market Covent Garden was a very cool place, there's even a very large Apple Store near by, not that I care, I'm an Android and PC user personally.
We really like old marketplaces, so much life happens around them. We're also food-people, so that also draws us to marketplaces. We like to watch where people go, what they order, etc. Then we try to order like the locals do, eating what they eat.
