you can wear shorts & any type of t-shirt/tank to a 1 TS restaurant, you can actually wear them to the 2 TS restaurant too - (except for not wearing a tank top for men). & these are the signature ones, the dinner shows & Brown Derby are exceptions to this. I wouldnt wear shorts to 2 TS restaurant but you can, and a plain t-shirt as well, again I wouldn't but there aren't many restrictions on the 2 TS restaurants
