Hi Peter , First of all , for what its worth , my advice would be to buy an advance ticket if you haven't already done so . For me , the catering fixed facilities provide both good hot and cold food in a service area between the 2 exhibition halls . These are supplemented by an internal mobile snack bar at the far end of the display hall , together with separate ice cream and drink bars around the service area. The greatest problem I have found is not with getting served , but rather with getting selfish people to either vacate their seats when they have finished eating , or to remove their bags from vacant seats to stop others sharing their table. Hence , I always take my own lightweight seating facilities and because the parking can be very/ relatively close to the exhibition , its no problem for me to store in the car until needed. Hope this helps.
