what restaurants/cafes spending voucher

Hi,

we were given some Thomson voucher as we had a delay, were not given them until we were getting on the plane so could not use them for food that day, we have another flight booked going from Stansted airport at the end of the year so could use them then but done know where we can use them in the airport, they just say for use of food/drink in flight or airport.

does anyone know where we can use them?
