Second only to the Serpentine Pavilion knees-up, the London art world’s next big bash is preview night at the Summer Exhibition. The RA’s patchwork submission-based show has been going since 1769 and is wonderfully accessible. Yet the big focus on the exhibitions means a lot of people don’t know that Michelangelo’s Taddei Tondo (the artist’s only marble sculpture in Britain) is in the permanent collection. You’ll also find next-level jamón sandwiches at José Pizarro’s café Poster Bar.
