When you report to a boss in a restaurant who only knows how to dish out criticism, but never serves a compliment, you have other choices besides quitting. You can always quit, but if you enjoy many aspects of the job, you should see if there is a way to get things to work here first.
Since the key source of your job dissatisfaction is the working relationship with your boss, you should meet with him. Tell him that you want to bring him up to date on a number of key developments in the restaurant. Within this framework, give him a clear idea of the broad range of responsibilities that you are handling, and let him see the measurable value that results from your individual effort. You should also tell him that you understand the need for negative feedback when due, but you would appreciate more constructive feedback and guidance in such situations, along with some credit and recognition when merited by your performance.
If he continues to offer nothing but negative feedback, and if this is deeply undercutting your job satisfaction, then it may indeed be time to fold up the menu and move on to a more palatable offering elsewhere.
