It’s a blustery, drizzly, foggy winter’s day. A day that might normally send you straight back to bed to take refuge under the covers, a cup of tea and a pile of good books close by. But we’ve got a lunch date. In San Gimignano. So, fuelled with coffee, we hop on a train from Florence to Poggibonsi where we meet my good friend, Sarah, a San Gimignano local.
