Good connections and excellent flower arrangements. The shops are handy for refreshments when on the move. Note that it gets very cold in winter, especially on the exposed islandplatforms.
Really overpriced food and drinks, but there's a good variety of magazines in the newsagents shop. If you have enough time, walk over to the tescos opposite to buy your food and drink.
Don't leave your bicycle outside the station, especially if you're away for a day or late at night. The cctv doesn't cover it and stuff get pinched from there all the time.
