Originally constructed to celebrate the turn of the third millennium, the O2 is now home to a large entertainment arena, a host of restaurants, a cinema and more. Standing at 52 metres tall, climbers embark on a guided exhibition across the iconic building, which is decked out with a walkway, suspended 2 metres above the tent-life roof. Get started with a briefing, before kitting up in a climb suit, gripped boots and a safety harness. Take a break on the observation platform at the summit and check out the expansive views of London. After, head to Cabana and savour a tasty three course set menu lunch with a beer, glass of wine or soft drink.Pick from delicious Brazilian street food dishes, such as crispy squid and butterflied Malagueta chicken
