Lots of people dream of opening a restaurant, but it is a LOT of work. Not being there everyday in the beginning doesn´t sound too realistic unless you have a partner (not a manager, but someone you know for years) who will be there all the time, at least for the first year. Expect 12-16 hour days. I love to cook but have worked in restaurants and couldn´t deal with the hours and stress.
Have you worked in a restaurant before?
