What types of soda are available at All Star Sports fountain?

We are going to be there in early Dec and my husband wants to know what types of soda are available for the refillable mugs. Is there a diet non-caffiene drink available?

You should be able to see all the soda options here:

Thank you for that link. I see diet coke and coke zero. I was hoping there would be a caffeine free diet available for him also.
