I'm curious how common seeing a photo of a dish at a restaurant will sway one over just a textual description. I find I go to a place for one particular dish that I fell in love with, yet hesitate to try something new.
I tend to eat the same things over and over, however, photos have exposed me to dishes I wouldn't have thought to try based on name alone but that visually fit some of my criteria for awesomeness: Ball shaped? Pancake shaped? Squishy? Noodly?
