It is a three-part collection documenting a number of live performances in 2014, as well as the recording and production of the band's 2015 tenth studio album Wonder Days.

Presented in three parts, All You Can Eat consists of Live at RAK Studio 1, recorded at London's RAK Studios on 4 November 2014, Live at the Brooklyn Bowl, recorded at The O2's Brooklyn Bowl two days later, and Wonder Days: The Film, a behind the scenes documentary filmed during the recording of Wonder Days, as well as footage from the band's appearance at Loud Park Festival on 19 October 2014 and highlights from the RAK Studios and Brooklyn Bowl performances.

[1] At the beginning of the year, the band's second guitarist and keyboardist Ben Matthews was diagnosed with head and neck cancer, which excluded him from taking part in any of the shows and much of the album's recording.
