Out of that lot only been to Barrowlands, but I get what you mean, like it's proper nitty gritty Glasgow and not that polished plastic turd kind of feeling like the Hydro ect.
I've been there once years back for Peter Andre (free ticket, don't judge me) and from what I remember the whole feeling of the place was very odd & hollow. Only time I'm in it now is for a smaller comic con every June.
