Washington, D.C. – October 17, 2026 -- Five Guys has a new blackberry milkshake in stores through the middle of August, and shoppers at about 155 locations in DC, Maryland and Virginia can get a free reusable tumbler with it.
The shake is built around Marion blackberries
The seasonal shake highlights Marion and other blackberry varieties. Five Guys describes the flavor as both sweet and tart, and says each shake is hand-spun and thick.
Three mix-in combos are suggested
Customers can pair the blackberry shake with strawberry and/or Oreo for a berry-crunch effect. Banana is another option, as is peanut butter for a PB&J-style shake. Any of the chain's free mix-ins also work.
The tumbler offer has tight limits
The giveaway applies only to in-store blackberry milkshake purchases. Online orders and delivery orders, including those placed through third-party platforms, do not qualify.
Tumblers go out on a first-come, first-served basis, with one per transaction while supplies last.
