@eyespy: No advice. Just one experience. At Freddy's, two people ate too much food and spent less than the Sassie company's reimbursement. We shared the fries from the combo meal. We shared the sundae. For us, this was too much food. We like the food, but we can eat only so much tasty stuff. YMMV.
About the picture: you can try to position yourself with your back to the counter or employees who might be working in the dining area so that you are not noticed for photographing your food. But this is not as important as the fact that you are to taste the burger and fries while they are hot, and you must photograph the burger before you taste it. So, take the burger image asap regardless of where you must sit. Then, taste the food. After that, you have time to evaluate other parts of the restaurant.
I would do this shop again. I would always bring a guest. That is just me.
