If you want to see out the window at the South Terminal there are a couple of options. Frankie & Bennies upstairs has a good-ish view over the apron and there is another similar eating place with a view over Pier 1. It's only a quick five minutes down to the gates at Stand 17-24 on Pier 2 which have really good apron views and a coffee shop as well shold you wish to get away from the shops.
Just keep an eye on the screens and know when you need to be at your gate
