Zburger Frozen Happy Hour!

On Mondays the Tenleytown Zburger does Frozen Happy Hour from 3-6pm where milkshakes are only $0.99! I am not sure if this is only at the Tenleytown location or if other locations participate as well. Be sure to ask for the frozen happy our special when you order though because although Zburger still does the special they no longer have the sign up advertising it and sometimes they don't automatically adjust the price.
