For its seasonal changes, the rose garden, the Serpentine, the Serpentine gallery, the Summer pavilions, the café etc.

 Great sourdough bread, beautiful pastries and Roman-style pizza slices. 

Cordings situated in piccadilly is a renowned establishment for British Country clothing and tailoring - that can not only kit you out to shoot pheasant in the finest yellow ochre cords but for me offers a great selection of socks.

In terms of materials and form, these galleries offer so much. On an abstract and typographic level, so useful. This is a section of an altar frieze, from the Eye Temple at Tell Brak (N.E. Syria), dated 3300–3000BC. The Egyptian rooms take the tourist weight; these spaces are much quieter and amenable time spent drawing and thinking.

Hotter than hell, but always a good night had. It can be whatever you want it to be - restaurant, pub, or club, has good outside space and rentable rooms, and plays an interesting mix of music to an interesting mix of people. The building is actually kinda beautiful too.
