Visit the Davies Alpine House and experience the high-altitude conditions that allow alpine plants to grow, take a trip to the desert to the jungle at Princess of Wales Conservatory, marvel at treacherous carnivorous plants and take in sweeping views of London from atop the Great Pagoda.

Brick Lane is the heart of London’s Bangladeshi community. Road signs here appear in both English and Bengali, and the restaurants are authentic and unpretentious. Some iconic restaurants like the Bengal Village, Aladin, Smokestak, Hawksmoor, All Star Lanes can be found here. Beigel Bake, where you can get a traditional Jewish-style filled bagel with salt beef or smoked salmon is an absolute must.
