Usually window shopping is for things you want to buy rather than experiences you wish to have or share.
Restaurants are a beautiful example of the later. When I pass a restaurant I have never been to (or even one I have not been to for a long time) I intermediately imagine the experience and who I'd like to share that with.
This image of 'Cosi' in in the city was a hand held shot made through the window well after closing. A few minutes later the lights were out and all was dark.
