Beautiful, modern train station with both national and international railway services, including high speed trains. Open and large so it doesn't get too crowded. Plenty of shops, including the essential M&S, WHSmith and Boots, and free access to toilets. Plenty of places to sit down for a bite as well, and just one escalator away from the Victoria, Piccadilly, Northern, Metropolitan, Circle, and Hammersmith & City lines.
