Ah! That's interesting. I was a student 2006-2010 and I recall getting cupcakes from Vanbrugh (they were well known for them). I guess the established bakery perhaps wasn't an official thing back then. Not sure.
I'm afraid I don't recall meeting CL and I didn't know her personally. I very likely did see her in the Roger Kirk though, especially if she served food as well as cooked. Interestingly, I don't remember ever seeing any police presence in the uni around the time. I would have thought there would be but apparently not... ?
Sorry -- I've edited the post to correct the link. It's the campus interactive map.
I've attached a pic where I've marked on the place I think CL is walking through in the foyer pics. It's a common route through the back towards the Roger Kirk Centre. I'm not sure why she would be coming from that direction if I'm correct though.
