Boy if you ask me, and hey, you did! My
opinion would be to stay in Law School. For a couple of reasons. You can always go to Cooking school and if you are a lawyer you can most likely afford it. If you are a cook who wants to go to LAw school it's not as easy. The point being that the salary being an attorney will afford you will give you more financial freedom than a chef will in most cases.
Part of what I loved about being a chef was that to a certain extent there was always something different, but wait a darn minute there. What about cooking the same thing day in and day out, with the exception of specials. Not always as exciting as may have been hoped. Running a decorating line for a dessert company I would watch 10,000 Key Lime Pies go past me and I knew that next week and the week after that and the week after that it would be the same. I wasn't sitting behind a desk thank god, but there was more than one day that I wished I had. Now due to the health problems all this wrought I am back behind a desk and wishing I could manage both!
Again my point being that the "prestige" that comes with being an attorney can take you pretty far in cooking. You have a built in proven learning ability. How many wildly successful people do you see that you find out started as attornies. You could end up being an R&D Chef that ends up becoming President of the company. You could become a Patent Attorney that specializes in food manufacturing equipment. You could use your Law school knowledge to become a food writer on food history as it relates to food safety history, laws, etc.
I could go on and on, but I'll leave it alone and say to you
keep cooking on the side, learn and in a few years take a break from the Law, stretch out your wings in a restaurant or two and do what you really want. That way you will have 2 careers to fall back on and take from what you need.
Either way I wish you the best of luck and if you become a Patent Attorney, call me I could use you!
