4. RUDY'S BAR & GRILLE // CHICAGO

Rudy’s is known for marrying alcohol and ice cream. Meet the Milkshake Martini: These Smirnoff vodka-based cocktails are combined with Homer's gourmet ice cream—which, legend has it, was a favorite of Al Capone's—to create a variety of flavors like Pumpkin Spice, Double Chocolate, and Dreamsicle.

5. GO BURGER // NEW YORK CITY

Go Burger is all about that gourmet hamburger experience, but their extensive selection of adult beverages really seals the deal. Not only do they have adult floats (including a mouth-watering take on the classic root beer float spiked with Elijah Craig bourbon), but their shakes and cocktails also won’t disappoint. Try the Grandma’s Treat, which is made with Maker’s Mark, caramel and vanilla ice cream.

6. WUBURGER // BOSTON

WuBurger is a staple for burgers, but their milkshakes should not be overlooked. A particularly intriguing one, the Hummingbird, is made with banana chips, chocolate, and raspberry liquor. At $12, that sounds like a steal.

7. RELISH BURGER BISTRO // SCOTTSDALE, ARIZONA

Relish Burger Bistro is housed within Scottsdale's luxury resort, The Phoenician. The menu [PDF] consists of various 100 percent Wagyu beef burgers on brioche buns, and when it comes to boozy shakes, it sticks to the three main classics: Chocolate, vanilla, and the root beer float. (The chocolate version is spiked with both Van Gogh chocolate vodka and Godiva chocolate liqueur.)

8. HOLSTEINS // LAS VEGAS, PORTLAND, AND ORANGE COUNTY, CALIFORNIA

Holsteins is not messing around with their mind-blowing variety of "Bam-boozled Shakes." Of the 11 shakes they offer (including a vegan coconut raspberry option), the liquor ranges from tequila (the Coffee & Donuts has Patron) to dark rum (the Bananas Foster features Myers's). And of course they carry flavored vodkas, like in the Campfire Smores shake made with Smirnoff marshmallow vodka, chocolate, marshmallow, and graham cracker crumble.

9. SKILLET // SEATTLE

What pairs perfectly with a burger at Skillet? A boozy milkshake with all of the decadence of a sundae! Their Colonel Parker hard shake adds bourbon to a peanut butter and vanilla ice cream base, while the Jesse's Peppermint Patty combines Batch 206 Mad Mint vodka and Meletti Cioccolato liqueur with vanilla ice cream.

10. FIELDING'S WOOD GRILL // THE WOODLANDS, TEXAS

Grab lunch or dinner at Fielding’s Wood Grill—but save plenty of room for dessert. Whether you have a hankering for the B 52 (with Cointreau, Bailey's and Kahlua) or a Bourbon Caramel (with Buffalo Trace Kentucky bourbon and toffee), the housemade ice cream made from local dairy is the best way to wash down a meal.

11. PALLOOKAVILLE FINE FOODS // ATLANTA

The options are (nearly) endless at Pallookaville. Their extensive list of Shaketails and Boozecreams pretty much guarantees that anyone seeking a boozy float will be satisfied.
