Wine me.
It doesn't matter what city you go to, these days you'll almost always find a decent establishment that serves quality wines. But if you're wanting to make the most of your visit, do yourself a favour and leave your preconceptions at the door and put yourself in the hands of the person pouring the drinks. If it's a good place, they'll be passionate and unpretentious and introduce you to a new world of flavours. Let go and embrace it, and save the 'glass of white' for when you're back home.
