I am with you LR - if it was all dingy smoky bars, cheap grub (maybe even some live music) I would go all the time!!
As it is, it is a plastic-fantastic wholesome-family venue - so riff-raff like me stay out. Possibly that fits withg their marketing plan as I won't spend as much money as some KPMG Consultant with no frontal lobes.
Just on the subject of Vinopolis, I used to work for an org which hired the space for an event, and I must say the interior halls are quite a beautiful set of spaces, although it's definitely not cheap to hire.
In the hire space it is definitely possible to avoid the aesthetic of 'KPMG Consultant with no frontal lobes' (heh heh, lol red bus) because it has a bare brick kind of look across a vast aircraft hangar type of hall. I guess an interior designer might call it 'distressed'? (which may then be the opposite of lobotomised consultant style, who knows)
