Why walk here for the coffee
Six minutes to one entrance — which one you surface at moves the walk more than that figure does. Coffee before the train or after it: come up, walk south into the banking blocks and away from the market crowd, and we are open from 07:00 until 23:00, which covers the first train and the last.
