6. Colorado: Sassafras American Eatery
> Location: Denver
A Southern-accented breakfast-and-lunch restaurant using local and organic ingredients, Sassafras gets a little wild with its shakes. Cap’n Crunch, chocolate-dipped bacon, banana cream pie, and honey vanilla chai are some of the flavors available.
7. Connecticut: AC Petersen Farm
> Location: West Hartford
The shakes at this 1939-vintage ice cream parlor and café are made with Petersen’s own ice cream and syrups, mixed in an old-style Hamilton Beach machine, and served in a soda fountain glass with a stainless steel cup full of the overflow on the side. Petersen’s will make a shake from any one of its 40 ice cream flavors, but reports that vanilla is the most popular. (There is a second Petersen’s location in Old Lyme.)
8. Delaware: Charcoal Pit
> Location: Wilmington
The original location of Charcoal Pit has been serving “secret recipe” burgers and other diner fare as well as “old fashioned hand-dipped” shakes in frosted containers to local diners for 63 years (there is a newer site elsewhere in Wilmington). The shakes may be ordered “triple thick” — and the triple-thick strawberry version has been hailed in particular.
9. Florida: Cousteau’s Waffle & Milkshake Bar
> Location: St. Augustine
Cousteau owner Stephen DiMares’s father and grandfather once worked overhauling famed oceanographer Jacques Cousteau’s boat the Calypso, and DiMares named his Belgian waffle milkshake shop after the celebrated Frenchman. His menu items, however, are named for places and characters in the Bill Murray movie “The Life Aquatic with Steve Zissou.” Among the specialty milkshakes that means things like the Papa Steve (blackberry cheesecake and homemade blackberry sauce), the Be Still Cody (chocolate with espresso, mocha sauce, and espresso whipped cream), and the Pele Dos Santos (vanilla with bananas and Nutella).
10. Georgia: Leopold’s Ice Cream
> Location: Savannah
In addition to the standard flavors, Leopold’s — owned by Hollywood producer Stratton Leopold (“Mission: Impossible III,” “The Wolfman”), son of the parlor’s founder — will make a shake from any of its ice cream flavors. These include tutti frutti, rum bisque, lemon custard, honey almond and cream, and (around the holidays) eggnog and frozen hot cocoa.
