[QUOTE="Doesnotcompute"] There's one piece of corridor where the floor is clear plastic/glass. There's a staircase below it, and there is no alternative but to go over it. It's just big enough that you probably need 2 steps across to clear it.[/QUOTE] They've put some clear glass floor like this at the top of the stairs in the Nottingham Fat Cat, it's great having a lunchtime pint and watching people freak out as they cross it. I suspect it'll be gone by spring though as anyone stood at the bar gets a view of people passing the ladies toilets, should they happen to look up.
