How old do you have to be to work at Denny's?

You have to be at least 16 years old to work at Denny's. The positions available for a 16-year-old are host/hostess, busser, dishwasher, and server. These positions are often seen as entry-level, so there are no additional requirements for beginning work, although having an open schedule for working is extremely beneficial.

While Denny's does hire people at 16, some positions require you to be older. You cannot work as a cook if you are under 18. Similarly, positions in management require you to be at least 18 and to also have previous experience working in restaurants.
