Veggie-tastic at the Museum of Garden History (interior by Dow Jones)

London is full of those moments when you think: "I can't believe that after all these years I have never been here before". And so it is with the Garden Museum, located in a wonderful 14th century former St Mary at Lambeth church adjoining Lambeth Palace, on the south bank of the Thames.

The building is a treat, and it's hard to think it was threatened with demolition back in the 1970s. The veggie café is excellent - I had a tasty Moroccan fruity vegetable tagine, which came with some fab salads. You can choose to sit inside, surrounded by tombs and monuments, or in the churchyard garden.

The museum's interior was revamped in 2008, designed by London-based Dow Jones architects. The building itself was left untouched, the museum housed in a free-standing timber structure constructed between the stone pillars and arches. It's well worth a visit even if, like us, it was just for food rather than to enjoy the exhibitions.
