If you have the O2 PRIORTY MOMENTS APP or can access it online ( http://www.o2priority.co.uk/moments ) then read on:
Free lunch and a drink (11am - 3pm). Only on O2
Includes free soft drink or coffee and a freshly made baguette of your choice. This is a great deal if you have one of these close by as this can cost you easily nearly a fiver !
