Dry Ice Factory. Byrne loves to ride his bike around towns he's in to explore from ground level. There's no double meaning to the dry ice factory other than he likely biked past one, it was probably fairly deserted and he pulled over for a break to get some thinking done. No mystery. Plus dry ice? What a concept.
Not sure why London is a small city. Unless it's a small-minded city. Or Byrne's version of London is a small area he sticks to.
