The City of London is definitely in the top 5 cities of the World. The amount of city workers that flood the square mile every morning is unbelievable. All these people no doubt go out to restaurants and local places to eat. Takeaways are huge part of it as there's quite a few places where you can order fresh stone-baked pizza, sandwich or sushi platters for those meetings or hot Indian curry for delivery in city. Late night deliveries straight to your office are also available.
