Lots of different things, depending where and when you're sniffing. That'd be the sensible answer. But far more fun to ask Google. Here are the top 10 relevant search results to the inquiry "London smells of":
- A very ill founded sense of superiority and smugness
- Roses by comparison (to Delhi)
- Frying onions
A heady brew, we're sure you'd agree.
We also polled our Facebook readers, and they suggested:
Pizza, Iron, Pavement pizza, Garlic, Fried chicken and chips, Exhaust fumes, Middle-aged spirit, urine, home, Aspiration...no perspiration, seasoning, curry, ruthless ambition.
The iron/railings/rust theme came up a few times. Can't say we've ever noticed this puzzling aroma.
What does London smell like to you?
