with so many dead in such an urban surrounding, and not a situation of mass destruction to city infrastructure itself, there should be plenty to scavenge...
Yeah a plague would leave all buildings and shops standing for our own use, I'd certainly hang around in the city til til the corpses started to stink and cause disease. (in both Survivor series they had to get out into the country for that reason)
..My first thought would be.... crap....all the hot chicks are dead....Of course, if this happened to me in Britain, I'd probably try to stock up on curry.

Isn't there an Indian restaurant on every corner right next to the pub?
Yeah but it's mostly drunk Scotsmen puking their guts up on street corners throughout England.
As for hot chicks, there'll probably be some around after Doomsday, this one will suit me fine, I'll hop in her plane with her and say
"Okay baby, fly us to Vegas!"
PS- my apologies to any Scotsmen here, I know they're a fine hospitable race.
For example an englishman goes to live in a remote cottage in the scottish highlands, and that evening there's a knock at the door.
He opens it and there's a big hairy Jock standing there in kilt, tam-o-shanter, sporran and all.
"Och laddie" he says, "welcome to the highlands, I live in a cottage down the glen and i'd like to invite you over for a party, there'll be lots of drinking, singing, dancing and wild sex!"
"Wow thanks, I'd be delighted!" says the englishman, "how many people will be there?"
"Just the two of us" replies the scotsman..
