There were no Scottish products apart from 1 bottle of a cheap blend of whisky you could get from any supermarket.
Last time i went there was the "BA Tartan Army", 1 stall that didn't appear to be selling anything, the "tolkien" society and a guy with some Galician bagpipes who appeared to be lost.
I don't think the Embassy sent anyone to try and promote tourism in scotland or anything like that either.
Still if they somehow managed to get some irn-bru. Save me a bottle!
