Nice touch from the Bishopsgate Kitchen in London: a twist on the old book of matches thing. The ‘You should grow some’ sits in the ‘here’s a nice idea for you’ camp of conversational communication, rather than the increasingly common ‘here’s something you should do – it’s good for the environment’ nudge nudge camp of smiley hectoring. The green’s rather fetching too. There’s a subtle link back into the restaurant and its use of herbs and spices. And it’s the sort of thing you grab as you leave and then hand out to friends. It has reminded me to go back and eat there again. Idea planted.
