By this I mean the food court that's right outside the ticket machines for
entering the station. There are two sections to that, we will probably be
quite close to the ticket machines, but if not then look around a bit.
Why not the level 2 food court? I think that one has more variety and caters better for tea. I think the lower ground food court mainly caters for lunch, and places are often selling left overs (sometimes at discount prices) at tea time.
