Your flight is scheduled to be operated by a Boeing 737-800(winglets) Aircraft. Inflight Entertainment is proveded by drop down screens above the seats which are located at roughly every 5 rows.
Normally it would be some BBC repeats or a film if time permits. You need headphone in order to be able to listen to the audio. These can be purchased on the aircraft or you can take your own. Aircraft are normally twin pin headphones so you would need an adaptor, such as
this from Maplin.
Food that would be available would be typically snack type things that most airlines would serve.
