Update 2: The Creek Stone Farms supplies Halal meat for export to the Middle East Shake Shack locations. The US locations do not use halal meat.
Update 1: Apparently Creek Stone Farms supplies Shake Shack with their beef. This farm’s beef is halal. Shake Shake doesn’t know this that’s why they don’t advertise it nor acknowledge it.
Sorry but it’s not halal. I kept hearing about this restaurant and there were rumors that they were halal. I decided to simply ask them, and they responded with a clear and definite answer.
Unfortunately we don’t serve halal or kosher meat in the US. I’m sorry about that, and hope you can visit us to enjoy a sweet treat of frozen custard.
