Radio Times are celebrating the best of TV, radio and books with a host of stars and TV insiders appearing on The Green at Hampton Court Palace for the Radio Times Festival. Every ticket includes access to gourmet food stalls, a shopping village, free events and screenings. Steph and Dom are the stars of the Channel 4 series Gogglebox and they're very kindly willing to share their very particular opinions on modern manners in celebration of their new book. Join them as they enter their top five faux pas into the Radio Times Vault Of Shame in a discussion that covers everything from cocktail making and pronunciation to dress codes and dinner parties. This kinda advice usually costs a lot more than what you're getting it for. Under 5 years go free, but must be seated on parents lap. Over 16s must purchase an adult ticket.
