Well what can I say about Panda? If you discount the greasiness of the food and the lack of authenticity of the "Chinese" it is trying to replicate, you get a very very good fast food meal. That being said it all depends on whether you are in the mood for fast food (thus expect grease) and/or authentic Chinese food.
Evaluating the place as a whole from the fast food perspective, it is very tasty, tons of different options at a decent price for the amount of food you get, so this category is very competitive.
I would recommend the pork eggrolls, not the spring rolls, as they are very good.
