just got back from the food show at the nec and it was great, really enjoyed it. saw gordon ramsey's show which was really funny. personally, i wouldn't bother with the wine glass (which costs �5) as all the wine/beer/drinks places give you plastic cups anyway, and when you do hold out your wine glass they only give you the same amount, i thought the wine glasses were a rip off.
i bought some kitchen devils knives and a pair of scissors, a pair of very modern steel salad servers, and a turkey baster. ate loads of free samples of cheese, sausage, olives, chocolate.
there's lots of walking to do, so you may find it a bit tiring at 8 months pregnant, the usual queues for the ladies loos, and not many places to just sit and rest. i thoroughly enjoyed it and will probably go again next year (there's one in june 2009 too).
