Were they faded jeans? Could it be something local?
The main website states: Because some of our locations vary slightly on dress code, please check with your local Ruth's Chris on dress code or check their location page.
In other locations is similar like the Baltimore and NC locations: "Thank you for not wearing: Athletic wear, tank tops (gentlemen), clothing with offensive graphics or language, flip flops, cut-off shorts or torn clothing."
In NYC it states "proper business casual for the dining area" which they translate as "Thank you for not wearing:
Gym wear, sweat pants, track suits, cut off shorts, tank tops, clothing with offensive graphics or language, midriff-baring outfits or exposed undergarments." For the lounge/bar they accept "casual dress" which is translated as "Expected attire should be free of offensive graphics or language. No exposed undergarments please."
I've been doing RC even when they were shopped by the MS that does the peanut loving burger! Yes, I know people are shocked, but the MS actually experimented with fine dining for some time and high fashion luxury designers but they decided not to pursue as they could not find anyone to shop with their insulting lowball they started the shops.But the reports were so easy, and the editors a breeze.
