While in Oxford, I painted my nails in Christchurch Meadow (you have to get creative when you're living in a room with 11 other people) and managed to get locked inside a downtown cafe. Long story, but for a solid hour I was trapped inside Art Cafe surrounded by baked goods and free wifi, which if you think about it, was kind of a dream come true.
Having to go to the post office, I found myself in the historic Jericho neighborhood which was originally a place for travelers to rest if they reached the city after the gates had closed. Now it has hippie book stores, cute cafe's and a stunning pottery shop, Illyria, that's owned by a lovely American with great curls.
