Most catering outlets have a view outside - about the only place in the terminal that you can see daylight.
The Granary / Sbarro has a smoking area.
The Shakespeare pub is small and overcrowds easily.
A similar choice of food is available Airside with two restaurants, a coffee shop and a sea food bar available in addition to the ubiquitous Heathrow pub for that last minute taste of English beer.
