Well, this website: http://www.kayak.com/ is amazing. I must say, there isn't an option for food porn but that besides the point. Kayak essentially compiles all other search engines and airlines into one easy search. When I was looking at multi-city flights earlier I had so many options turn up I was rather entertained. Searching for the airline, airport, liquor stores or whatever is half the fun for me. Straight to the point, Kayak is great.
The Terminal, now with more food porn.
