Exits from burger bars could certainly be made larger, but I suspect that isn't the intention of the suggestion. You may be interested in this link Vomitorium.
Quite agree that bacon flavour ice-cream sounds to me like a bad idea; the ruination of two good foods by consuming them together.
I like some combinations which others view with suspicion, cheese with apple pie, or fruitcake, or jam, are all good. So is treacle with Yorkshire pudding. I'll skip the bacon ice-cream, thank you (and Heston Blumenthal's scrambled egg variety merely confirms what I felt on hearing of his snail porridge; the man needs 'help')
