As a couple posters said earlier, yes a restaurant or establishment can enforce a dress code. But the question here is, WHO is this dress code meant for? I've grown up around a multiracial and multicultural environment. I have many friend and family members from different backgrounds and races. So not overt, there is some sense here on who they are trying to limit.
Their website says:
Baggy Clothing, Non-Military Issued Camouflage, Air Jordans, Air Force Ones, Polo Boots, Timberlands, Solid Tshirts, Sports Attire & Offensive Clothing
Those are very specific. It does not say sneakers. It specificlaly lists out Jordans and Air Force Ones. Dons't say boots, but specifically says Timberland's boots and Polo Boots. Dosn't say tshirts, but Solid Tshirts (meaning White Ts). Should I go on?
Come one man. If you still can't see it, it's because you don't want to.
