Continuing the mid-checkout-airport time-killing, we figure that Grand Central would be a good shelter from the rain. We quickly conclude that in order to be able to sit down, we’re going to have to actually buy something from somewhere, and this seems like the first reasonable place (Alasdair semi-jokingly suggests the oyster bar, but even I couldn’t manage it at that point in the day). A perfectly fine yuzu seltzer passes further time.
