Lawyers are not normally connected with industrial espionage, but the legal bods at Hunton & Williams haven't let that stop them.
Housed on floor 18 of the Gherkin, Hunton lawyers must normally descend to the first floor to catch a lift to the restaurant. However, many of them have been taking a detour via the 22nd floor.
The reason? As well housing a lift to the restaurant, it is also where Kirkland & Ellis's meeting rooms are situated. The glass walls allow a perfect view of which clients Kirkland lawyers are talking to. Maybe now they'll close the curtains?
