Be you, but do realize it is not McDonald's.
No formal dress code, but most patrons are at least "nice casual." Jeans and the like are fine.
I've seen as casual as jeans & t-shirt but many people there dress up nicer. So maybe tone it up a notch if you'd feel self conscious in that situation.
I don't think there is a dress code. I wore jeans and t-shirt.
