Coffe, Cake and Kink

London's only (so they say) kinky coffee shop. They sell coffee, tea, cake and erotica and pride themselves on being risque. In fact the atmosphere is more like having tea at a strangely comforting Aunt's house and the tea comes in generous pots which are more than enough for one. The service is solicitous and the cake delicious.

Bread

The bagel bakery on Brick lane has excellent Chola and rye bread. It is open at all hours, meaning that you can buy a soft, fresh, crusty loaf of rye bread with carraway seeds at 10.30 at night - if you wish to.

Boating

Todays activity...going to lunch by boat. caught a boat from Masthouse pier to St. Katherine's Dock and walked over Tower Bridge to the design museum. The boat goes by Canary warf and has great views as you approach Tower Bridge. You can take this boat all the way to Savoy Pier, past Tate Modern and London Bridge.

good cake

Tate modern members bar has good sandwiches, salads and excellent cake (pictured), particularly carrot. Also does strong coffee and has a fantastic view, seats outside when the weather is better. They open late on Fridays and maybe saturdays (check) and is the perfect place for a glass of wine after work overlooking the city and facing St. Pauls. You have to be a member (my membership has currently lapsed) which isn't cheap ( about £60 a year) but you also get free entrance to all of the exhibitions and private views (for an extra 20 quid).
Tate modern also does art.
