Why do you want to go to culinary school? If you want to be the next TV Chef Star - wrong motive. If you want to open your own restaurant - do a business degree and work in restaurants on the side.
I went to Culinary School but only after working in a few other careers. My goal from culinary school was to improve my home cooking not work in the industry. I was lucky enough to have the means and the time to graduate with no debt and I work in the culinary field as a private chef to keep myself occupied a few hours a week and in beer/toy money - far from a typical culinary graduate's life.
Before going to culinary school work in a restaurant for at least a year - try to start in the dishpit so you see how glamorous and demanding kitchen life is. The CIA requires 6 months work experience before they will take you.
A culinary degree is one of the few degrees you can earn which gives you a blue collar, manual labour job. At best you will earn just above minimum wage (the same you would earn with out the degree - note minimum wage is far from a living wage); work stupid long hours, when everyone else is having fun (nights, holidays, weekends are peak working times) and you will be sore all the time from cuts, burns, standing for 12+hours, lifting numerous 50lb boxes.
Culinary school can be a good option, but make sure you go in with your eyes open and forewarned what is on the other side.
