Want to cool off with a fun drink in a keepsake jar? Check out Yard Milkshake Bar at 341 Marietta St. NW, Atlanta. We parked next door at the Hilton Hotel parking deck and paid the $10 valet parking fee. There are other lots farther away and cheaper. They make these adorable themed milkshakes in a mason jar type glass they you get to keep. I will say you they.
