We visited the Geffrye Museum based on some recommendations from TA and what a jewel of a place. Even our teens enjoyed it. My husband has put it on his list of recommended places to visit in London. The garden in the back allows one to smell the herbs growing and is delightful to wander through, even on a dreary, rainy day (we've had fantastic weather the majority of our trip so no complaints). It does take some effort to find, but the reward is great.
