Casual or business casual is recommended. Show good personal hygiene, avoid torn or dirty clothing, and be considerate of the message potentially being sent by any graphics on your clothing (i.e. don't wear shirts with profane language or imagery).
Casual clothes. Don't show up in ripped clothes or clothes with profanity, but business attire is not necessary.
Its just using common sense
. You are going to a job interview.. u shower.. he fresh clean.. clothes clean.. no written profanity on clothes.. ripped up clothes..
Anything. Years of knowledge accumulated from being a fan of the restaurant.. that you obtained, somewhere..
Server attire// black clothes, big smile, high energy.
