i put about 17 or 18 years in restaurants, working my way up from dishwashing when i was 16 to executive chef by my late 20's (strictly big fish in a small pond).
rob b's advice about going in with your eyes open is absolutely right.
one of the best aspects of the business is the comaraderie working the line in a good kitchen. after you get to the point where you are able to come up with specials and can let your creative juices flow is nice too.
but,...
- don't expect to be exactly raking in the bucks. as a rule, wait people tend to bring home a lot more. i've worked in restaurants where the wait staff would be really pissed off if the didn't clear $200 a night, while the bulk of the kitchen staff were making between marginally more than minimum wage to about double minimum wage.
- if you get to head chef, your troubles are hitting full throttle, as you are usually putting in 12 hour days, dealing with people calling in sick, hiring and firing, purveyors, management breathing down your back, etc. etc. ad nauseum.
- don't expect to be working at "culinary art". 99% of the work in the food industry is pretty cut and dry and none too creative. you've got to put your time in to get to that position. come in, prep your station, sweat buckets for 3 or 4 hours, and then start cleaning up while late orders still come in.
- forget about thanksgiving and christmas at home.
when i started thinking about raising a family, i went back to college and became a teacher. part of me still longs for the better aspects of the job, but i can certainly do without the headaches and the grease.
my advice for those wanting into the business: put a couple of years in at a culinary school, taking every extra course they've got. enter some competitions. don't just take any old job, but try for the best restaurants and be persistant, going back year after year. accept the fact that initially at least, you'll have to put your time in as a drone, because even most people straight out of culinary school are still considered to know next to nothing. if you smoke, stop so you can clean your palate. your tongue is your most important tool. spend big bucks eating out at a variety of excellent restaurants (and bring a little notebook with you).
