All the world's great cities have some things in common and fantastic food is one of them. But what happens if a city doesn't have a chief restaurant critic? Besha Rodell, the recently appointed Chief Restaurant Critic for The Age and Good Weekend discusses the role of a great food writer and why she prefers to remain anonymous. Then it's time to visit Sydney's newest herbarium at the Australian Botanic Garden in Mount Annan. Denise Ora, Chief Executive of the Royal Botanic Gardens and Domain Trust, and Brett Summerell, Director Research and Chief Botanist, join Tim Entwisle for an amble through the new facility and discuss why they're critical to conserving plants and fighting climate change. Annie and Jonathan just can't get enough of the humble spud. In the latest edition of Kitchen Rudimental, Annie Smithers teaches Jonathan how to master a Potato Terrine with Gruyère. And finally, Colin Bisset explores the Tower House in London's Holland Park. It's the work of William Burges, an architect whose small but significant output represents a high point in the Gothic Revival. This is everything that minimalism is not.
