Greetings, Teresa. I'm so glad you stopped by the Disney Parks Moms Panel.
There really isn't an explicit dress code for
Steakhouse 55, or even at
Carthay Circle or
Napa Rose. Having recently dined at Steakhouse 55 for brunch, my attire was theme park casual (pants, blouse and thin sweater) as I was heading into Disneyland park immediately after. Fellow diners were similarly casual, and I saw some in shorts and sandals. (It was unusually warm for February!)
For dinner, business or resort casual attire would be appropriate, such as khakis and button-down or polo shirt for men, and a nice dress or slacks with blouse for women.
If you have further questions regarding your upcoming reservation at Steakhouse 55, please contact (714) 781-DINE and Cast Members are available to assist you.
I hope you'll find this information helpful. Come back to visit me on the Panel if you have further questions.
Bon appétit,
Kiki
