If you ever want a quick hot or cold drink while you are waiting a Finsbury Park for your tardy First Capital Connect train to whisk you northbound, be sure to stay in the station and get up to the little place sitting between platforms 5&6. They make a cracking hot chocolate for a very reasonable price especially considering it is in London! They also sell a range of tasty snacks, have very pleasant staff and pretty much everything is organic & fair-trade! Highly recommended, beats Starbucks or Costa any day.
