Le Cellier is very casual and what ever you wear to the park is acceptable. Some of the signature restaurants have a dress code but by all standards it is a very light dress code.
The official dress code at places like Narcoossee's, Yachtsman, or Citricos is jeans, skirt, or dress shorts with blouse, sweater or t-shirt, or a dress for ladies. For men it is dress slacks, jeans, trousers, or dress shorts, short-or long-sleeved shirt with a collar or t-shirt required. Jackets are optional.
Not permitted are tank tops, swimsuits or swimsuit cover-ups, hats for gentlemen, cut offs, or torn clothing of any kind.
