is this a good or bad job?
Decent. How old are you? It largely depends on what your managing as well.
bad resturants are for sociopathic assholes who dont have any future
also depend's if you're any good at being a manager
it can be ok if you dont mind the hours. you will be working a lot of nights and weekends. 50+ hours a week is not unusual if not normal. you dont have to sit at a desk all day and you have a lot of interaction with other people. depends on what you like but i work in a restaurant and the managers seem to like there jobs.
