i collect cafes. especially independent ones that don't have replicas sprouting up on every high-street. the photographers' gallery cafe has high ceilings and a linear seating made up square tables joined together to form a rectangle that cuts through the centre of the room. the walls, spotlit always have something interesting to offer. i am here to write my dissertation. i love writing at cafes. it gets my creativity going. it's got to do with the people and the space as well. there is the sporadic sound of the coffee machine. i had tea, not the best earl grey ever but my thick slice of lemon cake was sheer perfection. there was the sharp clean scent of citrus, a hint of grated zest and the whole thing just melted on the tongue. there is a nice selection of cakes (which made it hard to choose), apparently all supplied by Jo's who makes them at home. and there are also sandwiches which i haven't tried yet. however judging by the cake it's unlikely that the experience will be disappointing.
