And going to local stores and restaurants rather than chains might be better for the local community, but the big chain restaurants almost all have nutritional information posted on the web. Casa Playa and Mustards don't even seem to have websites, much less nutritional information there, and when i asked at Casa Playa in person they had no idea what the nutritional values for their stuff was either. And figuring it out by hand is a pain.
I suppose in another ten years every business in existence will have its own website, and maybe ten years after that we'll be able to take snapshots of our meals with cellphones (or whatever) and have a program analyze the picture to figure out the nutritional values. In the meantime i'm stuck with big chains or lots of math and guesswork =P
