Why are restaurants allowed to serve food like this!?

Ok so today at work, my manger and I decided to go get lunch. Well so I can stay on my life change, I looked up the restaurants around my job and I don't understand how they can serve stuff that bad!!!!!!

For instance there is a place that serves FABULOUS muffins with their salads. There is one that I am in love with and before I decided to get my life back together, I would eat two or three of these a week at lunch. Come to find out...that muffin is over 500 calories!!! WTF how is that possible!! So lets just say I am swearing off these muffins unless I have a really bad day and plan to hardly eat ANYTHING. I'm not even going to elaborate on how bad the food was for me. I am super stoked however at the fact that there is a mini dessert at a restaurant  that I love and it is sinfully delicious and only... 100 calories!!!!!! YEA at least not everything I was eating is completely bad :)

So today was my rest day (mainly because I am insanely sore) and so that means tomorrow I will be getting up early and probably will be taking my lunch to work tomorrow, that way I will know what I'm eating...
