You may not know what it’s called, but there’s no doubt that you have been exposed to it. You have probably even felt a little hungry after seeing it. You may have licked your lips and headed off to the kitchen or a restaurant for a taste of what you have seen. It may linger on your mind for days after, seducing you to stop in and give it a try. It’s called “food porn” and it’s increasingly becoming something that restaurants and food companies turn to in order to get your attention, get you salivating, and ultimately get you to buy.

“Food porn has a name just as interesting and exciting as the dishes it represents,” explains Ryan Fichter, Executive Chef of Thunder Burger and Bodega Spanish Tapas & Lounge, both located in the heart of Georgetown. “We are visual people and love to see pictures of great dishes. Like they say, a picture's worth a thousand words. One great food porn photo is all it takes.”
