GV gold class $30 does not include food. U pay only for the seat.
The difference of gold class from normal screening is that u get personal service like u got a waitress or waiter to serve your food up to your seat
GOld class have their own menu too .. like potato widgets etc. served hot
they also serve beers , wines ..
U also can go in 30 mins in advance to enjoy their services at the longue before going into the cinema
The seats also different.. is those u know aircraft 1st class seat , those inclined one can adjust to until lying on the bed one..
ya.. if any more services that i miss out welcome to add
